Four Color Theorem in Grasshopper

Hello, I’ve created a script that takes a surface that is divided up and randomly dispatchs them into 4 groups. I was wondering how I could take it further and have the 4 separate groups never border another from the same group like the four color theorem. IE: a red tile would never border another red tile. FourColors.gh (20.4 KB) I appreciate any help!
