This common dialog allows you to present a standard interface to allow the user to select and define a color. You can programmatically show or hide the custom color definition part of the dialog by default by specifying the FullOpen property, and you can predefine the set of custom colors by using the CustomColors property. Unfortunately, this betrays its interop origins, because the colors have to be specified as Int32 values encapsulating the ARGB color, rather than as an array of System.Drawing.Color values.

You can retrieve the user's selection through the System.Drawing.Color property.
