I know nothing about the jujibo controls but if they are descended from (or similar to) the standard controls, there should be no problem; only, instead of the button's, change the label's Font.Color.
Note that all this are just rather wild guesses both because my lack of knowledge and because you didn't show any of your code or the form's arrangement. Also, you titled the topic about a label, then talked about a button and now we're back to the label; it's almost impossible to even guess meaningfully about what you might really need ...
