Hi Guys,

i'm sorry if this is a really obvious question but this is my first tcl/tk program.
I have been asked to create a program that displays 9 buttons that are red and when clicked become blue and vise versa. I have the 9 buttons but am unsure as how to set the colours of the buttons, any help will be greatly appreciated.

Regards,
TMPS
