Ittens's 7 definitions of contrast:
Contrast of tone
Contrast of hue
Contrast of saturation
Contrast of extension
Contrast of temperature
Complementary colours
Simultaneous contrast
Contrast of Tone is the juxtaposition of light and dark values. It could be described as monochromatic.
-The highest tonal contrast is black and white.
-Perception is based on contrast.
-Red and orange have less tonal contrast in comparison to red and blue.
Contrast of Hue is the juxtaposition of different colours.
-For example blue stands out most compared to yellow and red on a white screen.
-Yellow stands out most on black compared to red and blue.
-High chromatic value and high contrast colours next to one another are distracting and and it can become hard to define where one colour ends and another begins.
-Tone and hue work together to generate a perception of colour and saturation.
Contrast of Saturation is the juxtaposition of light and dark values.
-Colour and optics
-Lighter/darker shades generate different ideas of, for example, the bluest shade.
Contrast of Extension is formed by assigning proportional field sizes in relation to the visual weight of a colour.
-Also known as the context of a proportion.
-Different amounts of a colour we see effects how well we can see and visualise colours.
-For example striped violet on yellow is less comfortable to look at than the same balance when placed block-on-block.
-Colour has a spacial quality.
-Equal use of colours doesn't always create a visual balance.
Contrast of Temperature is the juxtaposition of warm and cool colours.
-The association between temperature and colour.
-Red=hottest
-Blue=coolest
-Moving from red to crimson is a cooling of temperature
Contemporary Contrast is the juxtaposition of complementary colours.
-For example orange+blue or red+green
-The colours fight for attention.
Simultaneous Contrast is formed when boundaries between colours perceptually vibrate.
-If a colour is absent, the brain attempts to visualise it.
-For example green and yellow subtly merge into one. The yellow will then become slightly more orange because red is missing.
Task:
-Bring in 5 pieces of printed graphic design, covering a range of colour processes.
-Come back next week as a pair with a presentation/study exploring/explaining the relationship between high and low contrast.
-Individually document 10 different studies into colour and contrast (e.g. saturation/hue/tone/temperature) - find out what happens to colour when you deal with it relatively?
