Colour is an important part of theatre lighting as it influences our perception of the mood or atmosphere of what we see on the stage. It can be used to direct the audiences gaze to a particular area of a stage, to provide quick strong changes to what is happening on stage by using strong saturated colours, or subtly change our perception of what is happening on stage by using slow or imperceptible soft changes of pastel colours
The three variable of colour are :
Hue which is the position of the wavelength of the colour on the total spectrum.
Saturation which is the purity of a hue. Afully saturated colour such as primary red will have no other colout or wavelength in it. Adding other wavelengths or hues such as white will change to colour to pink.
Brightness is the capability of a hue to reflect or transmit light taking into account the light source and the reflecting surface.

If you are using LED lights on a lighting desk with basic faders you need to use one fader per LED control or DMX channel unless you know how to softpatch a desk that can have multiples DMX channels patched to one desk channel or fader.
The control of colour is not accurate as you are creating the colour visually by mixing the LED colours.
If you use a demo copy of LightFactory on a laptop, you can patch the LED fixture you are using into LightFactory, then select the LED in the Channel window, select the colour you want using Filters, then read the percentages of the colours on the fixture window and use those colours to set the lighting desk faders.
