Now for something completely different.  Here is a list of double stars whose components show a large amount of contrast in “COLOR”.  This list was compiled from a number of sources.  The “COLOR - KEY” was adapted from Webb Society Deep-Sky Observer’s Handbook:  Volume I Double Stars by Kenneth Glyn Jones.  Since the color of stars, as seen through the eyepiece can be very subjective, the “COLOR - KEY” will only serve as a guide.  You may not agree with the exact hues in the key, but I think you’ll agree these are some real beauties.
