A couple of bugs that shouldn't be too hard to fix ;) :
Entering a hex code by hand seems to be broken. It should be possible
and case-insensitive.
When a colour is entered by hand / from the colour picker it should
become an additional item at the end of the combo box with it's own
little pixmap. At the moment it seems to hijack an existing entry
without replacing the pixmap or even the text in the listbox.

believed things that were just ridiculous, and believed them so strongly
that you would have gotten in terrible trouble for saying otherwise."
