I've color corrected an image to exactly what I want on film.
Theres only 2 things I don't like
a strip of pink at the crossroads of shadow and light in the background and the subjects ears and nose being too red.
How do I get rid of this without effecting the shot look at all?

You'll have to play around with this a little to get it the way you want it but apply a matte and use masks to outline the area in question. Make the layer the reciprocal of the offending pink tint. Then using layer blend modes to tweak the color.

There are probably better/easier ways to do this but on one cup of coffee, that's my best suggestion.

Thank you.
Maybe get back to me after a couple of expressos?
