A good reason. However, it's good to do a quick search over Hackage
before uploading (or before writing) so you know what's out there.
Also, if you hadn't used an "AC-" prefix, you'd have had a name
collision. Is there a particular reason why you want your name in the
package name rather than just the author field?

Colour *is* complex. Which is why I'm so glad Russell O'Connor did all
the hard work for me :)

It provides darken, blend and addition (though addition is called
mappend rather than (+)). signum, abs and fromInteger don't make a
huge amount of sense for colours.

My feeling would be to trust the specializer until it lets me down.
Has it let you down in the past?
BTW, the EasyRaster package looks useful.
