chrominance chrominance a chromaticity coordinate in opponent-color luminance-chrominance color spaces (CIELAB, CIELUV, YcrCb, YIQ etc.), described by its position in relation to the red-green axis (a*, a’, Cr, I) and the blue-yellow axis (b*, b’, Cb, Q). This coordinate model of color components independent of the lightness level (luminance L*, L’, Y) assumes that a color cannot be tinted red and green, or blue and yellow, at the same time.
