Yah you can't fix color balance from bad color cast.

ALL photos look good with direct flash. Never use bounce flash. And indirect lighting is never flattering. EVER. Fire any photographer that ever uses bounce flash. Nobody wants their muddied color.

I was also a photo editor with thousands of photographer submissions. I can always tell which ones used bounce flash. A sure sign of unprofessional amateurness.

I get that people have a desire to maintain their lazy habits, but my job was to make sure they understood they sucked at photography.
