Colorful (based on the game MATCH ME! by OHTANI Tadashi and published by COLON ARC), is a co-op game about categorizing and matching colors as a group. Each turn a player will have a general topic, and must come up with a more specific example within that topic for the group to secretly match with a color card in their hand. After five rounds, cards are checked to see if the group was successful.
I have experienced this game with many different cultures. After translating it into English I’ve also added a competitive mode, and a team version that gives unique insights into what our perception of color is as a species, and how it differs between individuals.
