Hey there! No stress about the tags—math question categorization can feel overwhelming when you’re not a specialist, and we’re happy you came to ask for help.

To pinpoint where your disproof attempt might have gone off track, we’ll need a bit more context from you:

• Could you break down the specific steps of your reasoning? For example, did you create a map you believed needed 5 colors, or did you take issue with a particular part of the existing four color theorem proofs?
• If you built a counterexample, can you describe its structure? Even a rough outline helps—like how many regions it has, which regions are adjacent to each other, or if it has any unusual features (like a region completely surrounding others)?
• Did you work from a specific interpretation of the four color theorem that might differ from the standard one: any planar map can be colored with at most four colors such that no two adjacent regions share the same color?

Keep in mind that the four color theorem has been rigorously verified (first through computer-assisted proofs in the 1970s, later with more formal, human-checkable methods). Most disproof attempts stumble on subtle details—like accidentally creating a non-planar graph (which the theorem doesn’t cover) or misdefining what counts as "adjacent" regions. Sharing your reasoning will let us help you spot that flaw!
