H A Dext-ctrls-jpeg.rst51 - Use only luminance component.
70 without a need for direct reconfiguration of luminance and chrominance
H A Dcolorspaces.rst49 The Y value in the CIE XYZ colorspace corresponds to luminance. Often
58 define a color without the luminance component Y. It is very confusing
62 colorspace. Also, y has nothing to do with luminance. Together x and y
63 specify a color, and Y the luminance. That is really all you need to
