The difference comes down to how colors mix in light vs. paint:
ReplyDeleteMixing Red + Green Light = Yellow
Light mixes additively — you’re combining wavelengths of light.
Red light + Green light = your eyes see both colors at once, which the brain interprets as yellow.
This is called additive color mixing (used in screens, stage lights).
Mixing Red + Green Paint = Brown
Paint mixes subtractive-ly — pigments absorb (subtract) certain wavelengths and reflect others.
Red paint absorbs (subtracts) some colors, green paint absorbs others; together they absorb a lot, leaving a dull mix like brown.
This is called subtractive color mixing (used with paints, inks).
So:
Light = Additive mixing → brighter colors (red + green = yellow)
Paint = Subtractive mixing → muddier colors (red + green = brown).
