There's a simple online color picker here :-

The buttons in MythUI are very flexible  allowing you to chose various
methods for how the button backgrounds are drawn. You can use images you
draw yourself, images created by the theme engine that have a simple
gradient fill, or various simple shapes (currently boxes or rounded
boxes with or without a border and fill or gradient fill). It's up to
the themer which method to use.
  
The menu was the first thing to be ported to mythui and the existing
images where re-used for the menu buttons. When other parts of myth
where ported like the list buttons it was easier to use the images or
shapes which are automatically generated by myth rather than having to
create new images for everything. One big advantage of using shapes for
the background images is they can be resized to whatever size you want
and they still look good unlike images which will look either stretched
or squashed.
