Tsums are grouped by color so that similar colors will not appear together in a game. A Tsum may be pink and not red, but they will belong to the Red Color Family because they are close enough to red that it would be difficult to distinguish between a red Tsum and a pink Tsum while playing.
Note: This category will not be perfectly accurate because there's no hard data to define color groups. It's a lot of testing and retesting to determine color families.
This category has the following 11 subcategories, out of 11 total.
