I've had puzzles like this. I've had grid pattern rainbow trap platforms, prismatic of the similar type, and such forth. I was a dumb barbarian once, and solved it by dancing through it singing the Rainbow song my parents taught me. The DM thought it was hysterical to see clerical scholars and wizards baffled by it, and a dumb carefree barbarian jumps around.
I had a dial trap I made, numbers 1-9 on 3 or 4 dials... the clues was mathematical and you could solve it just by turning the dials persistantly. Of course when you hit certain numbers you get zapped with a lightning bolt... the elected player turned dials, got healed, and continued
broke through the door and seeked down the guy that commissioned and built it.
As far as the puzzle goes, get your GM to this post, have them post the result, and explain the theory and pattern. I'll keep taking a look, not giving up yet! but damn this things... not a puzzle as more a test for children to be trained as super secret Spies!
