Query: not for the red-green color blind

The open symbols are drawn with thin lines, and the cards use red and green as two of the colors. Red-green color blindness is fairly common, about 5% of males have it. And those who are red-green color blind can't play this game. I hope the game is reissued someday with a different set of colors.
