I don't think that purple was solvable without getting blue first or just sheer luck. There's no logic to it that would lead you to 4 of the 6 possibilities unless you'd gotten rid of two already. I saw it immediately but just couldn't narrow it down.
That's not clever Puzzle writing, it's just tricksy and smart-arsey.
