P: Is there a way to invert an Adjustment Brush mask?

[Jim_Palik]

I have a picture with mixed color from several different light sources (Florescent + Incandescent). I was able to adjust the color satisfactorily for the skin tones but this leave the background yellow-green. If possible, I want to mask the people (much smaller mask) and adjust only the background color.

Is it possible to invert the mask so that I can adjust the background colors?

I look forward to your reply

Jim
