Modify Colors

The Modify Colors section of the Substance Lab gives the option to modify the colors of the base texture defined in the previous section only in specific areas, according to a noise. For example, instead of wishing to redden your entire texture, you may want to apply red discolorations to only some areas of your texture, which can be done with this section. The yellow Select Noise box towards the bottom of this section is used to specify the locations of the texture that will receive the adjustments.

Property	Description
New Color	You may want to stain parts of your texture with a specific color. If so, this property specifies the color that will be used, while the property below controls the degree to which the color will be applied to the image.
New Color Strength	Controls the degree to which the color specified in the previous property will be applied to the image.
Brightness	Adjusts the brightness of the texture. As with all of these properties, the modifications will only be applied to those areas specified by the yellow Select Noise box at the bottom of the properties box.
Contrast	Adjusts the contrast of the texture.
Hue	Modifies the hue of the texture.
Saturation	Modifies the saturation of the texture.
Adjustment Area	Adjust this value to increase or decrease the total surface area that will receive the adjustments specified by the above properties.
Area Sharpness	Increasing this value leads to sharper transitions between the areas that will and will not receive the color adjustments specified by the above properties.

At the bottom of the Modify Colors section is a yellow Select Noise box that is responsible for controlling the locations of the texture that will receive the color adjustments specified by the properties described above. The options appearing within this box are identical to those of the Select Noise node. Please note that the Select Noise box will be grayed out (or disabled) if all of the above properties are set to neutral values that wouldn't result in any change in the image. If this is the case, first make adjustments in the properties above to enable the box.
