There are seven different contrast effects in the world of colours:
(1 ) The pure colour (hue) contrast:
This results when pure colours are used in random combinations. White and black can further enhance the vivid effect.
(2) The light dark contrast:
This is based on the use of different brightnesses and tone values of the colours. All colours can be lightened with white, and darkened with black. Tone scales which correspond to the light-dark scale (page 17) should first be made of each colour.
(3) The cold-warm contrast:
Its greatest effect is achieved with the colours orange-red and blue-green. All other colours appear cold or warm depending on their contrast with warmer or colder hues. (4) The complementary contrast:
In my colour circle the complementary colours occupy opposite positions. When they are mixed, the result is a neutral grey-black. When adjacent, complementary colours mutually intensify their luminosity to a maximum; when mixed, they extinguish each other to produce grey-black.
(5) The simultaneous contrast:
Its effect is derived from the law of complementary colours, according to which each pure colour physiologically demands its opposite colour - its complement. If this colour is absent, the eye will produce it simultaneously. Strong green makes neutral grey next to it appear reddish-grey, whereas the effect of strong red on the same grey is a greenish-grey appearance.
(6) The contrast of quality (colour saturation):
This is the contrast between luminous and dull colours. Colours can be subdued by the addition of black, white, grey, or complementary colours.
(7) The contrast of quantity:
This is based on the opposition of coloured areas of different sizes.
