A projector creates colour through
Additive mixing
Subjective mixing
Subtractive mixing
Attractive mixing
The principle of univariance says...
photoreceptor responses can vary in only one dimension
different light intensities can always be discriminated
different wavelengths cause different responses in photoreceptors
individual photoreceptors have no wavelength selectivity
A metamer is..
2 separate stimulus made up of different combinations of wavelengths appearing to be identical.
When the exactly the same wavelength in 2 stimuli are perceived as different colours.
A unit of measure in colour discrimination.
The colours that make up a perceived colour after additive mixing.
