Element of Design - Colour
Colour spaces
Colour is typically organized in a hierarchal fashion, based on how colours are mixed. You begin with the basic colours or primary colours, and you build up the remaining secondary or tertiary colours from these colours. A colour space helps to define how the colours are mixed, based on the medium in which the colors are used. There are two different kinds of colour spaces – subtractive and additive.
Subtractive: A subtractive colour space is the traditional colour space that most people refer to when they talk about colour. It is pigment-based colour, as in the mixing of paint. In a subtractive colour space, the colour pigments selectively subtract various wavelengths of light that hit the surface of the object and only reflect the wavelengths of light that our eyes see. The absence of any pigment produces white as all light waves are reflect, and all pigments blended together produces black as all light waves are absorbed (not reflected).
-
You start with the primary colour pigments: red, yellow, blue
-
You mix the primary colour pigments to create secondary colors: orange, green, violet
Additive: An additive colour space is an electronic colour space. It is light-based colour, as in the mixing of colour on the computer. In an additive colour space, different light waves are transmitted to the screen in differing amounts and are added together to produce different colours. The absence of any light is black, the presence of all light, or light at full intensity, is white.
-
You start with the transmission of primary colours: red, green, blue
-
You combine the primary colours to create secondary colours: yellow, magenta, cyan
