color-magnitude diagram

(CMD, CM)
(graph plotting stars' color to luminosity)

A color-magnitude diagram (CMD or CM) is a graph analogous to an H-R diagram, but plotting a color index against absolute magnitude (luminosity). It is often used for galaxies and groups of stars such as globular clusters.
