Challenger regulations regarding dice

[Chetote]

Hi,

The Challenger regulations document for official events reads this:

"Players must use official Marvel: Crisis Protocol dice. This 
includes the dice found in the Core Box, Dice Expansions, and/
or promotional material distributed by Atomic Mass Games. 
Players may not use replacement dice."

So I was wondering if I could paint the white reliefs in my dice in another color, to distinguish them from anyone else's dice.

Thanks.
