Quantifying Colour

Colours can be precisely quantified using numbers, with the LMS colour space representing all perceivable colours. However, this is not the standard way to describe colours, and instead RGB values are commonly used. The CIE XYZ colour space uses standardized primaries that are imaginary and do not correspond to physical quantities. Chromaticity spaces like xy chromaticity provide a convenient ...
