How to remove yellow in face in photoshop?

I think this one's pretty straightforward.

Color Balance is fine, easy to use and intuitive. But run through a luminosity mask. Blue with a hint of cyan.

I also get a slightly washed out feeling, so a Curves layer to "anchor" the shadows and juice up the contrast a little. That's all.

This neutralizes the overall balance, and also (to me) a credible skin color.

This is what i had after fixing her skin, somehow thinking i could do more

originally i used the hue stauration to bring down the colour of her skin which came up quite red

Hi Dennis

Thanks so much for the example ill check that out now. The shot on the right is her natural colour, brown and blonde not red.

Thanks, i know all the tools though not this advanced as yet to understand

Here is my 1/2-cent:

Since what she's wearing appears to be neutral toned in large areas, I eye-droppered on the gray-white stripe boundary on her right (our left) upper sleeve in the Camera Raw filter and that shifted the entire image slightly more blue and purple, removing a tiny bit of yellow and green.  I've added a few samplers to judge how neutral the areas are after the eye-droppering.   The lighter background and white stripe at her hip are close to neutral, now--samplers 1, 2, 7.  The remaining samplers on the darker floor and gray areas of clothing are less neutral, but more so than before the eye-droppered shift in color-balance.

Thankyou for your advice guys and i see the difference.

So i go into hue saturation or curves i get, though what do you mean by - use color range at the pixel level to select the really offending pixels to just give a slight shift to that color? i know how to slide up and down within different colours in hue/sat but i must have done something wrong, if thats what you mean. or is colour range different?

D Fosse is very good at this stuff. Here's my two cents. I see an ugly greenish gray that gives the impression of a yellow cast. The background has crossover (both blue and yellow), so when you try to desaturated the yellows, the more gray color still looks yellow next to the blue. I like to go in and use color range at the pixel level to select the really offending pixels to just give a slight shift to that color, using either hue/saturation and/or curves. Image on the left is with a slight tweak, and the image on the right is the original.

Yes, I recognize this yellow haze. I see it all the time.

The blue channel is inherently problematic with Bayer array camera sensors, very often resulting in an annoying yellow color cast, just like this.

I've found the best way to deal with it is simply to add blue with a luminosity mask, so that it mostly affects midtones/highlights. You really need the black in her outfit (more mid-gray here) to be neutral.

Nice shot.

Th exposure on her face through to the wall has yellow cast across both. Would have though it would be quite easy to pick up
