Damn, one away from a perfect reverse rainbow.

I worked out purple first, then what ended up being green. Was a bit stuck between blue and yellow. Worked out the category for yellow very easily, but couldn't quite nail down what went into it. Went on vibes and got it right. It was in the split second between hitting "submit" and the connection being revealed, that I worked out what blue actually was.
