Best Answer

Sladecolour produces a set of buttons designed for the blind and visually impaired that help to relate color to touch. The buttons match 16 colors each to their own unique shape. The buttons can be attached to canisters and containers to identify their contents or sewn to clothing to assist in putting together a color coordinated outfit.
