My guess would be that something odd is going on with respect to how
the colour is represented. For example it's very easy for two HSL
colours to be black, but not be equal (they have the same
lightness=0, but differing hue). You may need to write your own
routine to decide if they really do represent a black colour.

I'm not sure if I'm doing a compare wrong, but if I set my color
wheel to black (10.3.9, using the "named" colors/3 section from
left of color wheel), it doesn't seem to compare correctly:
if ([[colorWheel color] isEqual:[NSColor blackColor]])
doSomething; <--- never equals
Is there something further I need to do?
Thanks!
