Transparent or No Category Color or Manual #?????? Colors

[stlsprout]

I would like the option manually type my category colors like #AABBCC. It would also be nice to be able to make a transparent/no color option or turn off categories coloring altogether if not desired. I did it now with a template override, but just a suggestion.

AN interesting idea - basically this could be achieved using an override for administrator/com_jevnets/components/libraries/colours.html
