The Wedgits folks make a special "Class Pak" with six basic ("Junior") sets of 15 pieces each. All the different size or shape pieces in a set are the same color, and each of the six sets is in a different color.
This is quite a contrast to the regular sets, where no matter which set you get, the sizes are matched to their specific colors (WoW has different versions of the colors, but pretty much the same scheme). That means to build anything, you are largely obliged to mix all the colors in your structure. Which can create sensory overload for the autistic part of my brain.
The Class Pak is intended for classroom use, presumably helping the students sharing a workspace avoid sharing each others Wedgits.
But by using the full Class Pak, a lone builder can have every size or shape of basic Wedgit in each of six colors. Picking a limited palette can be not only easier on the eyes, but also create new aesthetic opportunities.
I usually combine the Class Pak with the regular Wedgits, which means that the count of Wedgits of different sizes varys depending on what colors are being used. Sometimes I use dice with the six colors on the faces to choose which colors to play with (you could use regular dice, and a simple number-to-color chart); duplicated colors in the dice roll means fewer colors in the play mix.
That should be fun. :)
