Port for linking color values.
This function will lead to a reduction of the color portions that have a mid-range brightness, especially if set to values of less than 0.5. Bias values greater than 0.5 will brighten the color portions with mid-range intensity correspondingly. Color portions that are already very dark or bright will be less affected. A Bias value of 0.5 will result in no changes to the colors that are input.
Similar to Bias, the Gain function will also brighten the three color portions and re-calculate according to the brightness that was ascertained. However, here the color portions with a mid-range brightness will be less affected.
Gain value of less than 0.5 amplify the brightness of color portions that are already in excess of 50% brightness. Color portions with a brightness of less than 50% will be darkened synchronous to this.
Gain values in excess of 0.5 will produce a different result. You can offset the brightness of all color portions near the mid-range brightness of 50%. With a Gain value of 1.0 you will in most cases generate a neutral gray tone.
