Love the concept, and the cleverness of using the idea for a simple but funny picture!

No, they don't. Yellow is a primary.

Well if it's red and green light, then maybe that does make yellow? I know how mixing colors work but not so sure how it works when it's light/reflected or whatever is going on there.

Thanks, Koreen. As soon as I saws this I figured he had some kind tongue in cheek in mind.

Red, blue and yellow are primary. Green (B/Y), orange (R/Y) and purple (B/R) are secondary. At least that's how it is with pigments. Light is different. Cute idea, but where you're going for yellow, I see Christmas.

Yes: when you mix light, red and green make yellow. (Red and blue make magenta, and green and blue make cyan. That's why printer ink comes in yellow, magenta, and cyan.)

If anyone is interested, I created a series of puzzles using afterimages of blue to get yellow. I included "yellow" in the title of each, for ease of searching. (userID kristen, and title yellow)
