// _font is an instance of org.newdawn.slick.UnicodeFont

// The initial problem stems from all the buttons being the wrong colour in the first place. The no text
// screenie has all the correct colours, but they are on the wrong buttons. The code setting the colours
// is correct. I've checked it a half dozen times. Theres no mixing orders, or swapping an R for a G
// value, or anything like that. The issue is definitely somewhere in the code in this paste. :-/
