I've not, only fingered Lorna's original copy. My approval is directed to mostly the box cover graphic design.
Are the colors of the pieces troublesome? Is this a colorblind issue?
I've seen people who aren't colorblind have problems with the colors. I imagine it is worse for colorblind players. I don't think I've ever been in a game where someone didn't make a mistake about the colors of the pieces, the black/white distinction, or both.
