Im always confused by RGB. I learned that if you want orange, you mix red and yellow. If you want green, you mix blue and yellow, if you want purple, you mix red and blue.

How is it that computers need green and not yellow?

Technology Connections has a couple interesting videos on the subject. Here's one focused on the color brown with an explanation of additive vs. subtractive color (mixing light vs. pigments) starting around this timestamp. There's also this video with some cool demonstrations using RGB LEDs and some common household objects.
