I think that I understand your last argument. And what I really have in
mind is a simple solution, more below...

I had to make RGB <-> HSL conversions, because it's more intuitive
change some color properties in the HSL color space. I thinked that we
could have something like GdkColor for other color spaces and functions
to convert between GdkColor and the other color spaces.

I think that it will help who want to play with colors in a quick way. I
don't find this in any other library, and I thinked that GTK+ could be a
good place for this, because it will become easiest to work with other
colors representations in GTK+ applications.
