BEN IK DAN EEN ONDERZOEKER?
IK BEN ALLEEN MAAR ZWAAR: IK VAL,
VAL ALDOOR – TOT IK OP DE GROND KOM.
Genua, januari 1882

Light fall/Mixing Light:
Mixing pigments is subtractive. Mixing light is additive. Let’s take the primary pigments, red, blue and yellow. Red pigment is red because the chemical it is made of absorbs (subtracts) blue and yellow light that falls on it and reflects only red light to your eye. Similarly, blue pigment is blue because it absorbs red and yellow light and reflects only blue.
So when you mix the three primary pigments together, you produce something that absorbs all of THE LIGHT FALLING ON IT in equal amounts and reflects nothing to your eye. Thus, it appears black.
In contrast, when you mix only red and blue light, there isn’t any yellow in it, so the resulting light appears purple (the complement of yellow). Likewise, if you mix red and yellow light it appears orange (the complement of blue). If you mix all three colors of light together (in equal amounts), the resulting light appears white because it contains all of the “colors” of the spectrum. This explanation is sound, although greatly simplified.
