Subtractive and additive colour mixing
Colour mixing is combining the effects of two or more lighting gels and can be either subtractive or additive:
- Subtractive - placing two different gels in front of the same lantern. Subtractive mixing is used to obtain a colour effect that is not available from stock or from manufacturers, although the wide range of available colours is so wide that the need for subtractive mixing is reducing. Combining colours in this way reduces the light towards blackness. The three primary colours of light (Red, Green and Blue) mix subtractively to form black (or to block all the light).
- Additive - focusing two differently coloured beams of light onto the same area (eg. Cyc Floods). Combining colours in this way adds the colours together, eventually arriving at white. The three primary colours additively mix to form white, as do the complementary colours.
