I decided to take a swing at MaizeGator's excellent Trichroma Paintomino series. I recommend checking them out if you haven't! The first one, with a visual example can be found Here

Divide each bold-outlined region into three differently sized sub-groups of cells. Then, assign one of three colors to each group so that each region contains exactly one group of each color. A digit in a cell indicates the size of that cell’s group.

Sub-groups that border one another through a bold region boundary may not be the same color OR the same shape (counting rotations and reflections as the same). For example, two touching S-tetrominos in different configurations is not allowed, but an S-tetromino may touch a T-tetromino.

When the colors of the sub-groups for each region are placed in order from largest to smallest, any pair of bordering regions must have a different order.
