Another posibility is to have container with label in it - you can customize their color settings as you wish. Just need to play with the SpecialEffect of the container and Click Event.

Note that this control will not be able to take focus - if you need this - one possibility is to ad an invisible button in the container, or change the label with ReadOnly TextBox (in the last option you will get a cursor in your "button" which is not so nice, duh).
No matter how you will decide to do this - you will need to make additional programming to have your fancy color button (you can even use shape - to make really cool buttons!)

Good Luck and Happy New Year!
