It tested my limited skills, but here is my bright cards for a themed PokerStars mod using a simple deck.
In the C:\Program Files\PokerStars\Gx\chips&deck\deck\simple folder are 7 folders marked 0-6, each has a file named cardbase that must be replaced by the following:
0:
1:
2:
3:
4:
5:
6:
Use at own risk until several of the smart guys here says it's OK.
