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?

Light vs pigment.

Computers use light, where the primary colors are Red, Blue and Green. Paint is in pigments, where the primary colors are Red, Yellow and Blue.

Just to clarify, with pigments (subtractive color mixing) the primary colors are in reality cyan, magenta, and yellow, which is why printers use CMY (and K, which is black). Blue and red are kinda close to cyan and magenta though, so those are sometimes stated as the primary colors along with yellow even though that's not exact
