COLOR MIXING Combining the effects of two or more lighting gels. 1) Additive : Focusing two differently colored beams of light onto the same area (e.g. cyc floods). Combining colors in this way adds the colors together, eventually arriving at white. The three primary colors additively mix to form white, as do the complementary colors. 2) Subtractive : Placing two different gels in front of the same lamp. Subtractive mixing is used to obtain a color effect that is not available from stock or from manufacturers. Because the ranges of color are so wide, the need for subtractive mixing is reducing. Combining colors in this way reduces the light towards blackness. The three primary colors mix subtractively to form black (or to block all the light).
