A new spectrally sharpened sensor basis to predict color naming, unique hues, and hue cancellation

<23>Significantly, and controversially, a simple RGB model of colour naming – used in computer graphics but not in perception - is found to accurately predict the World Colour Survey naming data. This both provides perceptual validity to graphics processing and teaches how this processing might be improved (by mapping from display to sharp RGB). Sharp RGB is a new tool that can potentially unify disparate theories of colour perception including unique hues and hue cancellation (demonstrated here). The role of sharp (RGB-type) sensors is part of the “Pixels to Perception” research programme proposed in Finlayson’s successful Royal Society-Wolfson merit award application.
