For future reference
This seems to be the most common kind of color deck. The minimum number of changes are made to the colors of the suits.
I've seen this style of color deck apear several times before in fiction, but Wikipedia doesn't even seem to know it exists. I like it, personally. Perhaps because it follows the Natural Color System, and thus apeals to my artristic sensibilities more? Idk.
This German color deck is designed so that the french suits more closely their traditional german counterparts (spades=leaves, diamonds=bells, clubs=acorns, hearts are the same).
