Two ForeColors?

Question

I need to create a custom control for an app. This would be similar to a Button, but with two possible forecolors for the text. I feel reasonably sure that this involves overriding the standard forecolor property, but I'm not sure how to accomplish this. Can you start me in the right direction? I'll have to work out the details for myself but I need to know if I'm even going in the right direction.
