One color and infinite variations thereof. What? Well the entire world of course. And beyond. The entire UNIVERSE. Sky earth water plants animals homo saps everything in existence. All blue. Foods clothes skin color eye color everything manufactured. Blue. Now how many hues of blue are there? That's where the variety and escape from boredom would reside.
I choose a blue world because blue is my favorite color. Especially a gray blue with silvery glittery sparkles. What color do you choose of which there would be an infinite variety and why?
