About pure & vivid colours
Pure colours
A pure colour is a single unique spectral colour and so a fully saturated colour produced by a single wavelength of light.
- In the context of colour, purity and saturation refer to the intensity of a hue.
- Unsaturated colours on the other hand can appear to be:
- Misty or milky the nearer they are to white.
- Dull and washed out as their hue disappears, leaving achromatic grey tones.
Vivid colours
The vividness of a colour refers to its brightness.
- When a colour is at its most vivid then it is at maximum brightness (100%).
- As colours lose their brightness they appear progressively darker in tone until at minimum brightness they appear black (0%).
