These can be either subtractive or additive. Subtractive: is when you place two different gels in front of the same lantern. It is used to gain a colour effect that can not be given from stock or from manufacturers. Although the wide range of available colours is so wide that the need for subtractive mixing is decreasing. Combining colours using subtractive reduces the light towards blacknes. Red, green and blue mix subtractively to form black. Additive: is when you focus two differently coloured beams of light onto the same area. Combining colours using additive adds the colours together which eventually arrives at white. Red, green and blue additively mix to form white and so do the complementary colours.
