Visual language - Colour theory

Definitions:

Additive colour: Light - RGB primaries, CRT monitors.
Subtractive colour: Ink, CMY Primaries, film prints.
Spectral wavelength: How the eye perceives colour.
Simultaneous contrast: Formed when boundaries between colours perceptually vibrate.

Eyes can be 'fooled' into seeing a full range of visible colours through the proportionate adjustment of just three colours; red, green and blue.

Itten's 7 contrasts

  • Tone - Formed by juxtaposition of the light and dark values. Colour wheel contains tone.
  • Hue
  • Saturation - To be more saturated; vibrant. A saturated blue will be the 'blueist blue' against de saturated blue's, the de-saturated blues may even look a different colour.
  • Extension - Formed by assigning proportional field sized in relation to the visual weight of a colour. Also known as contrast of proportion.
  • Tempreture
  • Complementary


Class exercise, experimenting with out coloured objects with others to see how they work with eachother.
