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.
