Can You Guess What Kind of Puzzle is This?

Are these genome sequences? Paint swatches? Part of the fun is figuring out what this puzzle is in the first place -and then figuring out the answers in the second place. Give it a try on your own. While many of you will know what’s going on right off, I must confess I was clueless when I first scanned this, until I saw the last one. Then it all became clear.

When you have exhausted all possibilities by guess, you can go here for the answers!
