When you look at the new decks of playing cards with new designs on them, nothing in the text describes what it looks like. There's only a colored ASCII picture.
Everyone can know what the design is supposed to be because of the item name, but only the adequately color-sighted people can know what color it is.
Update descriptions with text, please. Get at me on Fix-It with a list of these design names and I'll write the descriptions for you. I don't think I've seen them all in-game.
