Re: Applying masks to individual RGB channels

Put a little more work into it and came up with a two Layer (not 1 Layer solution). This solution requires no Layer Masks, the only Artwork transparency is for the border, no special Layer Style mode used, and you can slide any background under these two Layers and get the correct result.

I can give more details of its creation if this is of interest to the OP.

- The bottom Layer is the background
- The middle Layer is the solid color set to the same color as the color channel mask. Overlapping colors just add. This Layer acts as a color filter to only send the correct colors up the Layer stack from the background. This Layer is set to Multiply
- The upper Layer is the Gray gradient where each color channel mask zeros out that particular color in that image. Overlapping areas zeros out two of the colors. This Layer is set to Linear Dodge (Add).

First image is the entire stack with the Layers Panel
Next image is the Composite image which matches the OPs image
Next image is the top Layer in isolation
Next image is the middle Layer
Next image is the background Layer

Hope this is of some interest.

Stepped away and thought the thread went dormant.

John, that's a fascinating workaround! I didn't consider that or stumble upon it at all. Thanks for your attention.
