Pigment effect to color a MacOS X button?
I wan't to have a button that toggles between tinted green and red, without lightening its black text and normal shading effects, and I'd like to keep using the MacOS X look. But MacOS X buttons don't seem to allow changing the color of the button (setForeground colors the text, and setBackground colors the surrounding area).
New to Java programming as I am, I had the notion that I might be able to acheive this effect by overlaying the button with a green or red rectangle and displaying some kind of composite of the two.
My questions are 1) How can you get a true subtractive color (pigment) effect using composites? and 2) Would a button with a rectangle over it work anyway?
If you have any solutions or ideas, I would greatly appreciate knowing them. Showing me some code would also be very helpful. I'm just a lowly cognitive psychology grad student trying to design an experiment, and I've been giving myself a crash course in Java to get it done.
Thanks!
