When painting, black is the presence of all colors. Mix up red, blue & yellow (or green), and you will get black. Or you can deepen a color until it becomes black (think black leather with a blue tint).

Light is the opposite – mixing red, blue & yellow or green will give you white. I took a studio lighting course where our instructor did this and the result was just as the picture in the article above.

The first instance probably refers to solid colour – paint, for example – whilst the second refers to light. Mixing all the paints gives you black, mixing all the lights gives you white.

With light all colors combine to make white. With pigments all colors make black. Use a prism with light and you make a rainbow. I hope that image solidifies it for you.
