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?

    It’s just the concept of additive color mixing vs subtractive color mixing.

    Adding pigments together will ultimately create black. While adding more light together will ultimately make white.

    With pigments you’re taking away from the color space. You paint red to subdue all other colors except for red.

    But you use red light to make sure red is better seen.
