Core Syntax & Patterns
Find the Pattern Core
Look for the smallest group of colors that repeats.
Before you color, find the main pattern. Is it Red, Blue? Or is it Red, Blue, Yellow?
Repeat the Core
Use the pattern core to color all the shapes.
Once you find the pattern, just do it again and again until you are all done.
