[Sharkboy]

Hi,

I'm italian partial blind, excuse me for my bad english.

Because of my problems, I need to change the color of the pitch, I would like to make it black or dark green.

I would change:

- classic 2d match pich background color

- tactics pitch background color on tactics tab

I run several searches on the Internet, all with negative results. help me know?

Thanks a lot.

Alessandro
