Seastar Blanket: Color Order Research

When I was working on the additional color diagrams for the Seastar blanket pattern trying different color combinations, one moment I became curious if there are any color placement rules which might help to make a better decision.

Should I start with the lightest or darkest color? What color should I use as the last one? How does even a tiny change impact the overall look? ⁠
⁠
So I chose two sets of colors in the same color family and did research! This is so interesting to see how much of a difference small changes make!
