Very astute guesser.
That also explains why the forks are close to standard CMY colors. The left-most fork used a red filter blocking light, during the blue and green filters the white background shined through (Blue + Green = Cyan). Second fork was the green flash (Red + Blue = Magenta). Third fork was the blue flash (Green + Red = Yellow). I didn't actually plan the order. I gotta thank dumb luck for that.
I got the idea while I was playing with red and blue filters on the flash with a stationary fork from different angles. On the camera LCD I got a very cool electric-blue to electric-red gradiant on the tines of the fork, but when I pulled it up on my PC the red didn't quite match the blue. I must have bumped the camera. Two tries later and I got a decent enough shot to stop trying.
