Balancing RGB channels
Make small adjustments and use neutral areas as references. If an image looks too red, reduce red or add a small amount of blue and green. Large channel offsets can clip detail at zero or 255, so inspect bright and dark regions.

Yes. Small opposite-channel adjustments can reduce simple red, green, or blue casts.
