- Questioning colour
- Contextual and dependent on surrounding
- Spectral colour = colour evoked by a single wavelength of light within a visible spectrum
- Single wavelength or narrow band of wavelength generates monochromatic light
- Every wavelength of light perceived as a spectral colour in a continuous spectrum
- White = highly reflective colour
- Sky not blue, pure white light. Short wave lengths reflect off of articles and blue reflected
- Eye contains 2 kinds of receptors, rods and cones
- rods = convey shades of black, white and grey
- cones = allow the brain to perceive colour
- Combination of 2 cones = different colour
- Joseph Albers, Johannes Itten, iconic influences of colour theory
- Primary colours = red, blue and yellow
- RGB, usually screen based
- CYMK, for printing
- Hue, Tone and Saturation
