I feel it would be better to start cycling 2 colors, so that you naturally "catch" the reasoning you have to do. Then keep adding colors. It reminds me of the dual n-back game, where you had to remember N steps before of 2 things. You start with 1-back and progress once you "get it". As it is now, I just couldn't "get" what was the required reasoning behind this puzzle, before I got frustrated and left. And the hints didn't give me nothing personally, because once you get it, it basically solves it, without actually helping you understand the reasoning process. Also similar to Sudoku... if you start with a difficult one, you just get lost. You have to learn the reasoning tricks.
