Inputs
This setting can be used to link textures or colors that you want to affect or replace.
- Red, Green, Gray, Alpha: The intensity of the channel selected here will be used for the recoloring. If the selected components have a greater intensity, the colors will be taken from the right end of the gradient. For less intensity, the colors on the left end of the gradient will be used.
- Average: The three input color components will be added and the result divided by 3. The result will be transferred to the gradient to define the new color value.
- Length: The color will be interpreted as a vector from which a length can be calculated. The vector length is longest with white and shortest with black. The result can therefore also be converted to the gradient to calculate a new color assignment.
- Square Length: As with the Length option, the input color will first be interpreted as a vector whose length can be calculated. Finally, the value ascertained will be squared. This results in the results being smaller than with the Length option and have a tendency to get their colors from the left end of the gradient. Only the brighter colors will be gotten from the right end of the gradient.
- Brightness: The brightness of the input color will be placed at a position on the gradient from which the new color will then be taken.
- Sum: The input color components will be added and the result will be placed at a position on the gradient. Since values in excess of 1 can quickly be reached, a larger portion of the input colors will take their new color from the right end of the gradient.
- Minimum/Maximum: The smallest and largest components will be taken from the red, green and blue color portions and their intensity will be interpreted as a position on the gradient to define the new color value.
The color profile selected here will be applied prior to the output of the color gradient:
- Linear: All color and brightness values remain unchanged
- sRGB: A gamma value of 2.2 will be applied to the colors of the gradient prior to their output
