ESA Pro automaticlly calculates the RGB or RGBW values required to produce a specific color. However, certain fixtures calculate the RGBW color slightly differently. We can edit the way ESA Pro calculates the values from the options menu.
By default, the automatic adjustment of the white channel is linear.
LINEAR: If all the Red, Green, and Blue channels are lit to 30%, this 30% will be added by the white channel
SEMI-LINEAR: The white channel will stay at 0 unless there is ateast 50% of each color
EXPONENTIAL: The white channel will accellerate as the RGB values are raised. eg. If the RGB values are at 50%, the white fader is only at 5%. At 75%, the white fader is at 22%. Then in the last 25%, the white fader jumps up to 100%
You can also choose to have manual control of the white color fader if there is a specific color tone you wish to produce from your fixture
