Change To Color effect
The Change To Color effect (formerly Change Color HLS effect) changes a color you select in an image to another
color using hue, lightness, and saturation (HLS) values, leaving other colors unaffected.
Change To Color offers flexibility and options unavailable in the Change Color effect. These options include tolerance
sliders for hue, lightness, and saturation for exact color matching, and the ability to select the exact RGB values of the
target color that you want to change to.
Carl Larsen provides a video tutorial on the
that demonstrates the use of the Change To Color
effect to remove color fringes caused by chromatic aberration.
This effect works with 8-bpc and 16-bpc color.

From
The center of the color range to change.
To
The color to change matched pixels to.
To animate a color change, set keyframes or expressions for the To color.
Change
Which channels the effect affects.
Change By
How to change colors. Setting To Color performs a direct change of affected pixels to the target color.
Transforming To Color transforms affected pixel values toward the target color, using HLS interpolation; the amount
of change for each pixel depends on how close the color of the pixel is to the From color.
Tolerance
How much colors can differ from the From color and still be matched. Expand this control to reveal
separate sliders for Hue, Lightness, and Saturation values.
Note: Use the View Correction Matte option to better identify which pixels are matched and affected.
Softness
The amount of feather to use for the edges of the correction matte. Higher values create smoother transitions
between areas affected by the color change and unaffected areas.
View Correction Matte
Shows a grayscale matte that indicates the amount to which the effect affects each pixel. White
areas are changed the most, and dark areas are changed the least.
