I have currently made some hexagonal chiral structures that incorporate color change. Below are pictures of two of these structures that incorporate different color changes.
This chiral shape contains rubine red powder and blue castin craft dye. The change from purple to blue is depicted here.
This chiral contains blue powder and yellow castin craft dye. The change from blue to yellow is depicted here.
I have also been experimenting with using fabric with the colored polymer. Below are pictures of fabric incorporated into the polymer.
This chiral contains rubine red powder with blue dye and blue fabric has been super glued to the back of it.
This chiral has blue powder with yellow dye and yellow fabric super glued on the polymer.
