Some have estimated that one in 20 gamers are colorblind. Kotaku is one of them. Dapple was brought to their attention last week as a game specifically designed to include colorblind players.
Optimizing for a 5 percent minority is not a step many would think to take. Especially when the game is a matching puzzle based on the colors you get from mixing three paints with five other shades. Given that, can Dapple still pose a full-spectrum challenge to color-sighted gamers, without condescending to the colorblind?
