Colour in design: a short intro Richard Herriott Aarhus School of Architecture May 2014
Aim To remember that although colour is subjective, its effects are strong. Don’t leave the colour decisions to the end Product finishes and product geometry are completely inter-related.
How the eye sees colour https://www.pantone.com/pages/pantone/Pa ntone.aspx?pg=19357&ca=29 Provides a user- friendly intro to colour with more detail. https://www.pantone.com/pages/pantone/Pa ntone.aspx?pg=19357&ca=29
How the eye sees colour Light falls on the back of the eye. It is sensed by rods and cones: there are about 120 million rods and about 6 to 7 million cones, in the human eye. Cones sense colour Rods sense light/dark – more sensitive than the cones. This is why colour distinction fades before lines distinction.
Cones, our colour sensitive friends The cones are sensitive to red, green and blue. Which small square is darker?
Tired cones In a nutshell, exposure to one colour, e.g. a field of red will “tire” or desensitise the red receptors. Rapid exposure to a new image which is has low saturation (not very colourful) will make the image seem duller than if it was seen before- hand.

Primary colours To create all the colours of the rainbow, absorption or mixing use primary colours, which are colours that cannot be created by mixing other colours.
Secondary colours To get the secondary colours, mix the primaries two at a time.
Grey colours, pastel colours The “grey” colours are those primaries with black added (value) The pastels are those primaries with white added (less or more saturation)
Warm and cool colours Metaphors for the amount of red and blue in the colour. Warm colours advance while cool ones recede. Why? Cognitive psychology. In the distance, colours appear cooler (due to the water in the air absorbing the red.
Warm and cool colours
Neutrals Neutrals - Pure gray,( made of pure black, pure white) and brown are neutral colours. These aren’t on most color wheels but they’re considered neutral because they don’t contrast with many colours.
Contrasting and complimentary colour Or difference between colours. It is relative. Contrast of hue (red opposed to blue) Contrast of shade (blacker v deeper red) Contrast of saturation (whiter v purer red) Using these you can base a colour scheme: analogous colours or complimentary colours.

Colour study 3
Colour study 4
Colour study 5 (three colours)
Colour for design Formula: two analogous colour, one contrasting Make sure colours match assembly concept Avoid painting Keep it simple. Cheats: refer to Powerpoint slide design colours, or magazine layouts.
