  1. L: The L dimension of the space is roughly proportional to log-luminance and captures perceived changes along the black–white achromatic colour continuum. a, b: The a and b dimensions define a chromatic plane with axes corresponding to the red–green and blue–yellow opponent continua. c: Chroma is the perceived strength of a surface colour and the degree of visual difference from a neutral grey of the same lightness. H: Hue is the attribute of appearance that is often colloquially called colour
