You can protect an image
layer from any color adjustment by using a painted mask layer, a
selection tool (marquee or magic wand), or a mask shape. This example
uses a mask shape layer.
- Choose any curve creation tool. In the Paint Panel
set Type to Mask in
the Global Auto-Shape section.
- Create the curve around the rear indicator.
Note as you draw the curve, a mask is automatically created. In
this example we change the layer mask color to blue using the Construction
Plane Editor’s Canvas > Canvas General
Info window.
The rear indicator area is now protected from
any color changes.
- Choose Paint Edit > Color Correction > Color Balance .
- Adjust the Color Balance Factor to
50% and click any of the thumbnails to adjust the color balance.
Notice how the rear indicator color has not
changed because it was protected by the shape mask layer.
