Math Curiosity: The Coloring Problem

🔓 This is an unlocked sample! Byrdseed.TV is open for new memberships through April 30th, 2021. Join today!


How few colors do you need to color in any map so that no two neighboring regions are the same color?

Note: "neighboring" means that the regions share a side, not just a point. So New Mexico and Utah could be the same color on the US map as they only share a corner.

Thanks to Christine for sending in the Google Slides for this video.


  1. First, we introduce the idea of coloring in regions on a map with a very simple example that needs only three colors.
  2. Then, we increase the challenge a bit with a second map that still only needs three colors.
  3. Next, we present an even more challenging map.
  4. We reveal the coloring problem's true solution: no map needs more than four colors.


The registration window closes on April 30th, 2021
