If you have a custom palette and want to change the buttons on the Game, this is the code you need to add/change.

.wpbutton { font-family:arial,sans-serif; font-size:15px; color:#dfd48a; background-color: #455b2e; padding:2px; border:0px; border-radius:5px; border: 2px solid #000000; }
.wpbutton a:visited { font-family:arial,sans-serif; font-size:15px; color:#f5efca; background-color: #455b2e; padding:2px; }
.wpbutton a:link { font-family:arial,sans-serif; font-size:15px; color:#dfd48a; background-color: #455b2e; padding:2px; }
.wpbutton a:hover { font-family:arial,sans-serif; font-size:15px; color:#f5efca; background-color: #455b2e; padding:2px; }
