Make a new blank layer.

Make your selection on your original and copy it to the new layer and then blur.

I do not think your color cast will follow you to the new layer.

You still get the background contamination of the blur, even though you don't pick up the colors from the other layers. Gaussian averages a bunch of pixels and takes them from outside the selection as necessary.

The colored blocks below are all on separate layers, and notice the edge contamination on the gaussian layer, vs. the way lens blur handles it.
