Why mixing all colours of the rainbow creates white but mixing lots of paints creates brown
Subtractive vs additive light. Paint absorbs all light but the color they emit (red paint absorbs all light but red), light emits only the color (red light emits red light). When you mix two lights, you mix the wavelengths, when you mix paints you are combining what colors they absorb, mixing mor…
The Short Answer
Subtractive vs additive light. Paint absorbs all light but the color they emit (red paint absorbs all light but red), light emits only the color (red light emits red light). When you mix two lights, you mix the wavelengths, when you mix paints you are combining what colors they absorb, mixing more colors means they absorb more colors, leading the color they emit to turn very brown.
