Support for hex color values is much appreciated. I use them almost exclusively and it would be nice to make using them even easier by also putting the field right on this menu, perhaps near the bottom:
Better yet, activate and select the text right when it's opened so changing colors is simple as click, Ctrl+V, enter.
Currently it's click, click "Color Properties," select HEX #, Ctrl+V, click "OK" (modal Color Editor does not support committing with keyboard).
