A comparison between a typical normalized M cone's spectral sensitivity and the CIE 1931 luminosity function for a standard observer in photopic vision.. In the CIE 1931 model, Y is the luminance, Z is quasi-equal to blue (of CIE RGB), and X is a mix of the three CIE RGB curves chosen to be nonnegative (see § Definition of the CIE XYZ color space).
Color histograms are flexible constructs that can be built from images in various color spaces, whether RGB, rg chromaticity or any other color space of any dimension. A histogram of an image is produced first by discretization of the colors in the image into a number of bins, and counting the number of image pixels in each bin.

Example of an RGBA image composited over a checkerboard background. alpha is 0% at the top and 100% at the bottom. RGBA stands for red green blue alpha.While it is sometimes described as a color space, it is actually a three-channel RGB color model supplemented with a fourth alpha channel.
Subtractive color mixing An 1877 color photo by Louis Ducos du Hauron, a French pioneer of color photography.The overlapping subtractive yellow, cyan and red (magenta) image elements can be seen clearly along the edges of the image.
The following list shows a compact version of the colors in the list of colors A–F, G–M, and N–Z articles. The list shows the color swatch and its name. Hovering over the color box shows the HSV, RGB, and #hex values for the color in the tool tip.
