Hypercolor Thinking Putty is thermochromic - just a touch from your hands or a warm coffee mug will reveal a new "hot" colour. Allow it to cool off or stick it in the fridge, and the "cool" colour will be restored. When you need to adapt, reach for Chameleon Thinking Putty. It changes from a lush, tropical green into a bright fluorescent yellow right before your eyes.
