Why oh why couldn't you have ordered the colors by increasing frequency on the light spectrum, rather than arbitrarily as you have done?
That's the problem with these changing color games -- most people just pick some arbitrary order which you then must memorize to be halfway decent at the game, but the more such games you play the worse you become at all of them since one game's arbitrary order will be entirely different from another's and so forth and you'll be remembering some order from some other game or at the very least take longer to process the correct order for any given game as you'll have to mentally filter out all the other orders you've also memorized. This added bit of mental delay is enough to significantly impact gameplay to the point you might lose only because of this.
You easily could solve this by the very logical ordering of increasing frequency, while at the same time actually teaching people something.
