Just send them an e-mail, Bryan is super good about getting back to you. I got my buttons from them, the chrome bezeled ones. I LOVE them, swapped out the standard micro's for their 20g micros. Smooth as silk. I had my brother in law make a comment on how sweet they were, and he's not even a big aracade guy. Anyways, I had the same question regarding getting colored buttons and the same colored lights, colored lights and clear buttons or clear lights and colored buttons. He recommended I go with colored/colored. He even said that if I didn't like the way they looked, I could send them back and swap them out.
My admin buttons though, are clear with colored buttons, and i think they look good.
I would just e-mail him, tell him the look you are going for and I am sure he will help you out.
Oh and if you are looking for buttons, give his a shot. I dig them.
