How many different coulers do you need if you want to couler in counters so than no same couler are touching?

To color counters such that no two adjacent counters share the same color, you will need at least four different colors. This is based on the four-color theorem, which states that four colors are sufficient to color any planar map without adjacent regions sharing the same color. However, the exact number may vary depending on the specific arrangement of the counters.
