if you like to change the colour of your transparent buttons, here is my suggestion.

use the following link to oder a sample book (see attachment)
of gel filters

choose the colour, take a punch and you have a perfect sized filter for the transparent buttons. all you have to do is to push the filter all the way into the button and you´re done.

cheers
