The 5 Color Rule states that students must use at least five colors in all their drawings. The purpose is not so that drawings are pretty and colorful (although they do end up this way).
The five color theorem is a result from graph theory that given a plane separated into regions, such as a political map of the countries of the world, the regions may be colored using no more than five colors in such a way that no two adjacent regions receive the same color.
What is the 60-30-10 Rule? It's a classic decor rule that helps create a color palette for a space. It states that 60% of the room should be a dominant color, 30% should be the secondary color or texture and the last 10% should be an accent.

It's called the 80-20 rule and it's very simple: if you decorate 80% of a room in neutral colors, you can get very colorful with the other 20%.
While using the 6:3:1 Rule, designers have to choose a dominant color and use it in 60% of the space, a secondary color in 30% and a final color in the remaining 10%. The 6:3:1 rule eases the eye of users to move from one point to another comfortably.
