adda, it's not an issue with color balance in the game.
The things that stand out are "Famous" and "kickflips 'n biscuits" which are very faint in the game.
The adjustment in yellow opacity didn't pop the black text because they lack boldness. The v1 yellow actually popped fine in the game.
The red on Brockjangles has this weird multi-layered look since the lettering was custom so up close you see all the puzzle pieces.
At a moderate distance Brockjangles looks fine, but even up close the black words at top and bottom are barely readable in shade or light.
I wish I could show a high res pic to get across what I mean and not sound like an ungrateful ass as it appears I am coming across in this disription.

Summary: Thicker/Bolder lettering on "Famous" and "kickflips 'n biscuits" would make this I think as best as it can get. If that is not possible, then it is still a sick as fuck deck that I will rock with my pig pen as well.
