Is there a way to check whether two Colors are equal? If the Colors have
different Name properties, the = operator will return false even if the
A,R,G, and B properties are equal. I would like to be able to check whether
two colors are equal based only on the properties that determine what color
will be displayed. Is there a way to do this without writing my own method?
Thanks.
 
Both the Equals method and the = operator check for known colours. The only
way to check colour equality in a numerical manner is to compare the RGB
value. Probably the easiest way is to convert to integer and compare those.

If color1.ToArgb() = color2.ToArgb() Then
