Complex additive colour mixing system with three sides and three, four, five or six colours. The classic version with the three primary colours, RGB, lets you determine the colour triangle according to the wavelengths of each group of LEDs. The choice of wavelengths for the sources must favour the brightness/saturation ratio. Each RGB side can accommodate a complementary colour to increase light performance at the expense of colour space. This additive mixing system achieves colours that are more intense and up to six times brighter than a subtractive mixing system with a white source.
