I'll Decide ...
In my part of Scotland there used to be one or two teams that had black as their 1st kit
Did not cause me any issues as I had 3 coloured tops at the time (Red, Yellow and Black)
I am not aware of any rule or regulation up here that prevents a team wearing black. I am sure I shall be corrected if my last statement is incorrect
Maybe not up there mate, but down here it's generally a "refs will only wear black" rule.
