Colour psychology.
Some colours, such as blue naturally calm. It is argued that the meaning of a colour exists not because of cultural or social conditioning but it naturally makes us feel the way we do. Blood is naturally red, which connotes danger and pain- so the existing semiotics don't carry the colours meaning, they simple make it stronger.

The Trichromatic theory.
THE PRISM. The combination of three primary colours of light to re-create the entire spectrum is known as additive mixing. It starts form an absence of light. The light of each primary is added to produce progressively lighter tones. Mixing an equal amount of each primary results in 'white' light. For example, addative mixing is evident in TV screens/ Computers etc.

Additive and subtractive mixing.
The first model above is the Additive mixing (RGB), the second is Subtractive mixing (CMYK), and the third is Subtractive Mixing (RYB)
Onto Subtractive. Instead of pigments that absorb all but a certain primary, pigments that absorb only a certain primary are used. From white you can then reverse the additive process by applying more pigment, subtracting more of each primary until black is left. The colours that absorb the primaries are their complementaries. Cyan absorbs re, magenta absorbs green and yellow absorbs blue.
