Remember that with smartcurves, you can even create layers from the L*a*b a and b channels in Elements... details later on.

Thanks for the links! I'm going to try that action out tonight..

And I'll be anxiously awaiting more on the channel layers in smartcurves!

Here it is:
Test it with the following image:

First duplicate your background
Then use smarcurves with the Lab mode
- to keep only color and eliminate tones, move the lightness end points to get an horizontal line in the middle of the graph= 50% luminosity
- to eliminate the blue/yellow component (b), move the a component horizontally in the same position.
Click ok

The result goes from green to magenta (a channel)

To extract the color, add a green (or magenta) solid color fill in difference mode. Merge down (Ctrl E) and desaturate (Shift Ctrl U)
To get the most of the mask, use levels or auto levels (Shift ctrl L)

To extract the a channel, do the same by neutralizing the b channel and using blue or yellow solid color fill.
