JOHANNES ITTEN, ON CONTRAST

Posted on 09:45 by cena
Found a good article here by Lars. A. Bratterberg on Johannes Itten, the Swiss designer and theorist and important figure of the Bauhaus movement in the early 20th century. can be seen here

//


The research of Johannes Itten is important and should be understood by design practitioners who wish to employ contrast of colour to evoke a desired reaction in their design’s onlooker.
Colour is one of the elements of design; “[it] can make designs more visually interesting and aesthetic, and can reinforce the organization and meaning of elements in a design” (Lidwell, Holden, Butler, 2003). One of the more effective ways to use colour as an element is through exercising contrast. When in design, contrast illustrates an element in opposition. This essay will examine how the research and teachings of Johannes Itten aids practitioners to consciously make use of contrast in design. The examination will progress through looking at Itten’s seven contrasts.
Colour Theory, Design, Johannes Itten
Johannes Itten was a Swiss design teacher and theorist. He is considered to be one of the prominent figures in colour theory. After teaching his own art school in Vienna from 1916 to 1919, he joined the Bauhaus. The Bauhaus was an influential art school in Berlin where Itten would work as a Master, later publishing books based on the course he taught.
Itten devoted much of his work to the concern of colour harmony. He noted the common perception of harmonious colours were combinations of similar chroma. Colour theorist Wilhelm Ostwald writes in his book Primer of Colours, “certain combinations of different colours are pleasing, other displeasing or indifferent. (…) Groups of colours whose effect is pleasing, we call harmonious.” Itten on the other hand, opposes Ostwald in his statement, “(…) they are combinations of colours that meet without sharp contrast. As a rule, the assertion of harmony or discord simply refers to an agreeable-disagreeable or attractive-unattractive scale. Such judgments are personal sentiments without objective force. The concept of colour harmony should be removed from the realm of subjective attitude into that of objective principle” (Itten, 1970, p. 19).
Itten sought to bring theories of contrast into the objective perception of colour harmony he wished to create. In studying colour contrast, he made a “systematic and practical [oversight] to the special effects of colour contrast” (Itten, 1970, p.32). This oversight is commonly referred to as Itten’s seven contrasts. To understand the contrasts organized by Itten, one must have knowledge of his 12-hue colour circle. Entitled Farbkreis, it was a rework of the colour wheel by 18th century colour theorist Johann Wolfgang Goethe.
The colours that make up the middle triangle are the primary colours, yellow, red and blue. Primaries are absolute and cannot be attained by combining other colours. By mixing the primary colours two and two, it creates secondary colours that make up the hexagon shape around the triangle. The circle of sectors surrounding the hexagon and the triangle within is compromised of a primary and secondary colour at every third sector. The spaces between them are tertiary colours, the result of mixing primaries and secondaries (Itten, 1963).
Contrast of Hue
A contrast of hue is simply compromised by the visual difference of dissimilar hues. For the contrast to work, minimum three colours of clearly distinctive nature must be used. The polar hue contrast is attained by the combination of the primary colours, yellow/red/blue. The combination makes for a tonic, vigorous and decided effect (Itten, 1970). Though the primary colours are the instance of the most extreme contrast of hue, other colours can also be employed. The contrast’s intensity will however diminish as the colours move outwards in the colour wheel; using the secondary colours green, orange and violet weakens the effect, a drift the tertiary colours promote still.
By no means must the colours necessarily be of identical shapes and sizes as shown in the figure on the right. One colour can be given the dominant role, with others acting as supplements or accents. A colour’s character and strength will be changed by the emphasizing of its quantity, claims Itten.
The significance of this contrast involved the interplay of primeval luminous forces. The undiluted primaries and secondaries always have a character of aboriginal cosmic splendor as well as of concrete actuality. Therefore they serve equally well to portray a celestial coronation or a mundane still life.
- Johannes Itten
Light-Dark Contrast (Tone)
One finds the polarity of light-dark contrast in the opposition of black and white in their greatest saturations. Between them are the spectrum of chromatic colours and the continuous scale of grays; a massive range of different luminosities. The light-dark contrast is amongst the most expressive means of composition, and is an extremely important effect in design. Its importance is prominent both in polarity use and the rendering of light and shade on objects, giving the impression of three-dimensional forms.
Neutral gray is a characterless, achromatic colour, relying on contrasting shade and hue to influence itself, Itten proclaims; “any colour will instantly transform gray from its neutral, achromatic state to a complementary colour effect corresponding mathematically to the activating colour” (Itten, 1970, p. 37). Gray is dependent on other, nearby colours for character; mellowing their impact by absorbing their strength, it assumes a life of its own (Itten, 1963).
Somewhat more complicated is the light-dark contrast between chromatic and achromatic colours. When gray is used in a composition involving chromatics, the chromatic’s brilliance must be equal to that of the gray. However, when a range of chromatic colours are measured to a scale of grays between black and white, one can observe that the brilliance of undiluted chromatics complement different tones of gray.
Itten discovered that saturated, pure yellow is very light, as it matches one of the lightest grays, and discovered violet to be the darkest using the same method. For yellow to match the gray value complementary of violet, it must be darkened and thereby loses its radiant quality. Dark, pure yellow is no actual instance. Yellow and violet at full saturation are the chromatic colours with the strongest light-dark contrast (Itten, 1970).
Cold-Warm Contrast (temperature)
The presently accepted notion of colours with varying sensation of temperature was a matter Itten persevered in his studies and lecturing. Experiments have shown subjective feelings of heat or cold differ in environments of different colours: A room was painted blue-green, and another red-orange; “in the blue-green room occupants felt that [15° C] was cold, whereas in the red-orange room they did not feel cold until the temperature fell to [11-12° C]” (Itten, 1970, p. 45). The relationship of blue-green and red-orange has proven to be the polarity of cold-warm contrast.
Generally the colours through yellow to red-violet on the tertiary level of the colour wheel are considered warm, while the cold are the colours including and between violet and yellow-green. Though this is the common rule, the warmth is relative to the temperature of contrasting colours, as demonstrated in the figures to the right.
Cold-warm contrast has high potential as an element in pictorial design. The designer can control the feelings induced to spectators of a design, in addition to how colours will be perceived through their relation with other colours. Nevertheless, the designer must consciously exercise cold-warm contrast knowing the design not to employ other contrasts. A situation might occur where the design has more weighing in light-dark contrast than the cold-warm effect the designer sought for. To interweave more than one contrast should be avoided. Therefore it may be an advantage in a cold-warm composition to use colours only of equal light or dark (Itten, 1970).
Complementary Contrast
A colour is complementary to its own opposite. Directly opposite colours are located adjacent to each other on the colour wheel. A physical method for confirming colours to be complementary is through adding them together; if their mixed pigments produce a neutral gray, they are complementary. Furthermore, if one hue is excluded from the mix “the sum of all the other colours in the spectrum is the complementary of that hue” (Itten, 1970, p. 49).
Every pure colour has a complementary colour, and only one. They make for an initially strange pairing, but in a process yet to be explained, the human eye finds balance in them. If a colour is without its complementary, the eye will attempt to generate it. Examples of complementary colour pairings are: orange, blue; yellow, violet; green, red; and also tertiaries such as red-orange, blue-green. Complementary pairs frequently represent more than one contrast. Yellow and violet are not only complementary; they are also the polar light-dark contrast. Likewise red-orange and blue-green is the pair of extreme cold-warm contrast (Itten, 1970).
This principle [of balance in complementary contrast] is of great importance in all practical work with colour. In the section on concord of colours, we stated that the rule of complementaries is the basis of harmonious design because its observance establishes a precise equilibrium in the eye.
- Johannes Itten
Simultaneous Contrast
As briefly discussed under the subject of light-dark contrast and touched upon during the explaining of complementary contrast, the eye requires complementary colours to balance its impressions. This is the premise is simultaneous contrast, whose name derives from the generation of a colour’s complementary by the eye simultaneously as it views that colour.
An achromatic hue is the most apt medium for one colour’s complementary colour to produce itself in using simultaneous contrast. If a background of strong colour had a square of neutral gray with the exact brilliance as the background centered on it, the contrast would be in effect. The grey area would be coloured by the eye to have a suggestion of the background’s complementary colour. The effect is demonstrated in a figure under the subject of light-dark contrast. “Simultaneous contrast determines the aesthetic utility of colour,” stated Goethe (Itten, 1970, p. 54).
There are means of avoiding simultaneous contrast, as the effect is not always preferable. Using hues of different brilliance evens out the effect, as the contrast then will be that of light-dark. The example on the right shows orange with three slightly different hues of gray, their property of contrast vastly different.
Contrast of Saturation
Pure, luminous colours and those that have been subdued create a contrast. A contrast of saturation refers to the difference in quality of purity in colours; those with an intense impact and the dull, diluted.
Itten says pure colours can be diluted in four ways, each leaving them in a different state. Brightening the colour with white renders it rather colder. To darken colour with black deprives them, to different degrees, of their brilliance. Adding gray, or intermittingly black and white, to a colour, will lessen its intensity. Finally, mixing complementary colours will eventually produce a gray hue. The same applies to mixing the primaries, secondaries or all colours of the spectrum.
True contrast of saturation is found between intense and dull instances of the same hue. In saturation contrast of unlike hues there is a probability of other contrasts, such as cold-warm contrast, to spoil the impact of the saturation values.
Contrast of Extension
A contrast of extension is a contrast of colours in their relative sizes to each other. “Attention to the colour areas in composition is at least as important as the actual choice of colours. Any colour composition should be evolved from the relationships of elements of area to each other” (Itten, 1970, p. 62). In his research, Itten inquired as to how one could know the size of colour areas to make them balanced with regard to the force of the colours’ brilliance.
Itten extended upon the theoretical work of Goethe, in employing a system of numerical ratios to measure colour’s light value. The brilliance’s number value was estimated by comparison to gray scales, where it became clear that different hues have varying light value intensity. This was explained when dealing with the light-dark contrast, where it proved yellow to be the lightest and violet the darkest. The light values of the primary and secondary colours are found on the right.
Itten explains the process after the calculations have been made: “In converting these values to harmonious areas, I must take the reciprocals of the light values; that is, yellow being three times as strong, must occupy only one-third as much area as its complementary violet” (Itten, 1970, p. 59). Orange will occupy one-third of the complete area compromised by itself and the blue, while red and green have the same light value and will take up the same amount of space.
This essay has examined Johannes Itten’s systemized colour contrasts in the light of objective colour harmony and the theoretical knowledge of the 12-hue colour circle. It has shown the theories it presents holds great importance to design practitioners. The explanation of the seven contrasts outlines how to make correct use of them, in addition how not to mistakenly employ more than the contrast sought-for. The contrasts have different areas of use and should be used accordingly; each hold individual effects and reactions it imposes on an onlooker. Contrast in design is an important tool, designers should be fully aware of its properties.

COLOUR THEORY: ORANGE AND BLUE!

Posted on 10:51 by cena




Orange and blue are both complementary colours, as they're both opposite each other on the colour wheel. They're both primary colours and they both contrast and work off each other quite intensely, they both kind of fight for your attention. This sort of stuff was looked in depth in Freds 3rd and 4th Colour Theory lectures which I will be looking through on my blog very soon.

I've noticed orange and blue gets used ALOT for film posters and also in film scenes themselves, possibly because, as I said, they both fight for your attention so you get maximum levels of eye-catching..ness. It's pretty route one stuff for blockbuster posters nowadays. Check this out...

"Ever since the poster for 2002's The Bourne Identity, movie marketers have shown their true colors when touting action-oriented films. And those colors tend to be orange and blue, in a striking combination. ''Orange and blue are complementary colors, so just by nature they give you that jolt that you need,'' says veteran movie adman Charles Reimers, who designed Bourne's one-sheet. ''The studio's always saying 'Make it pop,' and those two are the big favorites because red and green just take you to Christmas.'' - Keith Stasciewicz (2010)

TINTS, TONES & SHADES

Posted on 13:07 by cena

If white is added to a colour, the colour is called a TINT

If gray is added, the colour is called a TONE

If the colour is made darker by adding black, it's called a SHADE

COLOUR THEORY LECTURES 1 +2 + NOTES

Posted on 13:53 by cena

Here are the general points I took away from the lectures and further points of investigation I hope to carry out.





There are two different types of colour.. additive and subtractive colour. Additive colour is basically RGB colour and subtractive colour is basically CMYK colour. It may be more complicated than this, but as of now this is the main information I'll be dealing with.


additive colour = RGB colour
subtractive colour = CMYK colour


RGB colour is obviously to do with light, and is based around the concept of white, and the colours that make up light waves. i.e. white. Isaac Newton back in the day found this out when he shined light through a prism and it split up the light into three principle colours: red, green and blue.


CMYK colour is where Cyan (C), Magenta (M), Yellow (Y) mix together to form Black (K). Sometimes called Key, or Kblack.


RGB colour is mainly based around screen, projectors, cameras, pixel based tools such as computer monitors. This is why RGB is used for web, so whatever colour you work with, it will display how it should and the colour won't change drastically. Similarly you should never work with CMYK colour modes, to produce work that will be displayed on the web. The different colour resolutions and colour modes of different monitors will make the colours work out differently.


CMYK is mainly to deal with print - offset printing, paints, plastics, fabrics, and photographic prints are all based on CMYK colour. Basically anything that comes out of a printer is CMYK colour. Most printers have seperate ink cartridges for C, M, Y and K. and mix them together to make pretty much any colour possible.


As it says in the E-Studio resource (probably explains better than me!)




"Additive Colour

An additive color model involves light emitted directly from a source or illuminant of some sort. The additive reproduction process usually uses red, green and blue light to produce the other colours. Combining one of these additive primary colors with another in equal amounts produces the additive secondary colors cyan, magenta, and yellow. Combining all three primary lights (colours) in equal intensities produces white.

Additive color systems start without light (black). Light sources of various wavelengths combine to make a color. In either type of system, three primary colors are combined to stimulate humans’ trichromatic color vision, sensed by the three types of cone cells in the eye, giving an apparently full range.

Subtractive colour
A subtractive color model explains the mixing of paints, dyes, inks, and natural colorants to create a full range of colours, each caused by subtracting (that is, absorbing) some wavelengths of light and reflecting the others. The color that a surface displays depends on which colours of the electromagnetic spectrum are reflected by it and therefore made visible.

Subtractive color systems start with light, presumably white light. Colored inks, paints, or filters between the viewer and the light source or reflective surface subtract wavelengths from the light, giving it color. If the incident light is other than white, our visual mechanisms are able to compensate well, but not perfectly, often giving a flawed impression of the "true" color of the surface."



It's really interesting to note that they're both the primarys and secondarys of each other. The secondarys of RGB are CMY and vice versa. how cool!



We also learned about colour terminologies and colour wheels and how each colour works with another. The three main types of colours are:

PRIMARY:
This depends on what type of colour system you're working with.

For additive colour the primary colours are R (red), G (green) and Blue.

For subtractive colour the primarys are C (Cyan) M (Magenta) Y (Yellow).

When light is split through a prism, the colours are sometimes called spectral colours which are ROYGBIV. These are often shortened to Red, Green, Blue/Violet. I learnt a nice little memorising thing in school:

Rip
Off
Your
Goolies
Before
I
Vomit


Red
Orange
Yellow
Green
Blue
Indigo
Violet


SECONDARY:
Secondary colours are the result of mixing two primary colours. For example Red and blue produce violet. Red and yellow produce orange. Yellow and blue produce green. Depending on what ratio of each primary you add you get different colours. For example a 'reddy yellow' or a 'bluey green'.

TERTIARY:
Tertiary colours are browns and greys, containing all three primary colours. They're created by mixing either all three primary colours or a primary and secondary color (secondary colours of course being made from two primaries). By varying the proportions of each primary color, you create the different tertiary colours.



COMPLEMENTARY:
Complementary colours are the colours opposite each other in the colour wheel. For example primary red's complimentary is primary green. Primary oranges complimentary is blue. Yellow's complimentary is Violet. 


CHROMATIC VALUE:
The 'lighter' a colour is, or the closer to white a colour is - the higher it's chromatic value. So for example pale yellow has a higher chromatic value than navy and black as it's lighter and closer to white than both.


Similarly black has a lower chromatic value than navy and pale yellow as it's 'darker' and further away from white than both.


HUE:
Hue is pretty much what we call different shades of colour. When we differentiate a cyan, from a turquoise or a navy blue. We are looking at different hues of colours blending together. Different hues are caused by different wavelengths of light, especially in regards to additive colour methods.


SATURATION:
Similar to chromatic value, where it deals with light and dark. A colour seeming lighter or darker in terms of how much light is hitting it. For example a colour on the wall, in a dark room would look different to a colour in a light room even though the colour on the wall hasn't actually changed but the amount of light hitting it. It looks as though someone just mixed more black, or white into the colour when you see it on screen/print. So it's easy to think of it in terms of light or dark, but really something should be weak in saturation or strong.






You can see here all the different shades of colour, as the colours go towards the outer edge, the chromatic value of the colour is increasing as they're getting lighter, or more 'whiter'.  In the middle area of all the colours in terms of the levels is probably the colours with the strongest saturation as they're the 'brightest',
