Colour

1. Subtractive blend or coloured pigments

   • Coloured pigments, or subtractive colours, absorb or take away the light's energy.
   • Cyan, magenta and yellow are the primary colours of the subtractive blend
     • Complementary colours of pigment, when blended, produce the colour black. Combining each primary co- lour with a secondary one creates them.
       • Blue-violet, red and green are secondary colours. They are formed by mixing two primary colours
         • Cyan + magenta = blue-violet
         • Magenta + yellow = red
         • Yellow + cyan = green

       • Lowest saturation
         • grey

6. Colour mixtures

   • colour harmony
     • is a combination of colours that produces attractive and balanced colour effects. We can create colour harmony by consonance or analogy
   • colour contrast
     • Contrast is produced when the colours in a composition do not have anything in common with each other

7. Colour classification system

8. Colour forms part of everything Newton successfully isolated a ray of white light. When he passed it through a glass prism, Newton discovered the ray became a spectrum of separate colours

9. cool and warm colour palettes

   • cool palette
   • warm palette
