@Andrius it's hard to figure out what module to use unless one can see the image in question. also it looks from the histyogram that WB is not adjusted properly
judging by the histogram - the peak is in the highlights, maybe this is a sunset - where a red peak is always on the brighter side, hence there is also blue shift.
anyway, there must be a patch with bright red.
virtually I'd try a channel mixer in the red channel, however would limit it strictly to lighter parts with drawn and/or parametric mask - this will allow smoothing the peak without touching the left side of the histogram.
then, if still an issue, I'd kill it with shifting the hue band in a color zone module, provided there is a mask to focus on the problematic area.
