First of all, this is by far the best skin I've ever used! The only thing I've changed are the colours of the attributes and how good a player is in a certain position. When I played my first match I noticed that the ball is nearly invisible. It took me a while to find it and first i thought it was the shadow of the ball, but it is the ball. It is just grey and really hard to spot when in motion. How can I change it to white? Thanks for the help!
