Checker Pattern That Spawns On Certain Parts

Hello, I am trying to make a checker pattern that only gets placed on certain blocks. Probably based of the color of the part, but I have no clue where to begin. What could I do to make this?

“checker pattern” can be pretty ambiguous, if you meant a checkboard pattern that appears on the surface of a part, you should probably apply a Texture on all 6 sides. You will need to find a suitable image to use as the texture (or upload your own).
