Polychrome

Okay, so polychrome is like having lots and lots of colors all in one thing. Like when you see a rainbow, you see lots of colors, right? Well, polychrome is kind of like that, but it's not just in the sky - it can be on things like artwork or buildings too! Instead of just being one color, polychrome things have many colors all mixed up together. It's kinda like when you mix different colors of play-doh together to make a new color - that's what polychrome is!
