Reduce Yellowishness (Warm Tone) on Face ?

[augustya]

Hi Guys,

There is this Photo which was captured by a phone camera which makes the skin look lot warmer, how can I reduce the yellowishness on the face look a little white a tad white, I mean and less yellowish ?

Have you tried white balance? Or HSL?

Only Levels and Curves did not like the end result. I was thinking white balance but then thought woukd ask you guys here. So what be your pick ? White Balance or HSL isn't HSL more for Saturation ? Which feature in HSL can do it ? Luminosity ?

White color in your canvas is white or yellow?

It depends on your individual goal. "Warm" can mean various aspects, e.g. yellow, orange, red (hue, H) but also brightness & darkness (luminance, L) or saturation (S). Since there exists various skin colours the range of possible results for "correct" colour modification is quite large and can't be done by the forum without knowing the person, respectively your goal.

If you want to achieve an impression of neutral light then White Balance is a good start. It's easier to judge if the image contains parts of obviously neutral colours like white or gray, which is not the case in your image. Different to other adjustments White Balance affects all colours in the image and thus it can prevent you from achieving a desired result: reducing yellow would increase blue for instance … etc. So, if you don't care for instance about the blueish shirt color then WB can be a wanted and already sufficient tool. Also, if the image is taken already with a light colour you want to achieve then using WB is not really necessary or can cause an unwanted result.

As second and main step I'd use HSL (which has a more flexible UI than e.g. Curves or Levels). You can either just "play" with the sliders – or, often more efficient, first decide in your mind what the result should look like + make the according corrections. So, if it seems to be too yellow adjust the yellow in HSL, if too red then red. If it feels too dark then move the L slider. Actually the colour well you choose to start with (e.g. yellow or red) is not that important because you can refine the affected image colours by the handles in the colour wheel, the six wells below the wheel can be used for any of the colour ranges – and thus they can be used in a inefficient way by corrections that cancel or contradict each other.

Here's a nice method that can neutralize the color cast that your phone camera has introduced. Put a Levels adjustment on top of the image. Instead of making initial adjustments to the "Master" channel, select each of the Red, Green, and Blue channels. In each of them, move the "Black" and "White" sliders so they just hit the shoulders of the histograms in each of the channels. Once, you've done all 3, you can tweak the result by moving the "Gamma" slider to either side. For instance, in your image (edited, shown below) I have moved Gamma to the right on the Red and Green channels, which effectively brings a bit more Blue and Magenta into the image, respectively. In the Blue channel, I've moved the Gamma slider just a smidge to the left, which introduces a bit more blue to the picture.

You can now visit the Master channel and tweak the sliders there, which are more for luminosity than for color.

Also, you could limit the change to the face (if you were so inclined) by inverting the adjustment layer (select the adjustment in the Layers panel, and choose Invert from the Layer menu), then painting in White directly on the adjustment to bring the adjustment back to those areas you want it to apply.

[By the way, I find this method to be really helpful when I'm trying to correct the color on scans of old, faded photos that have more color casts than a simple White Balance adjustment can effectively handle.]

There are lots of tutorial videos covering the topic of skin tone.

A simple (brutal) version is to mask all skin color (maybe except lips), and apply a gradient map with hue 30, sat 50%, and adjust lightness from 0 to 1 (hsl sliders). You need 3 nodes.

hsl

30 / 50 / 0

30 / 50 / 50

30 / 50 / 100

If unhappy with colors, use the middle node and play with hue or sat.
 

if the skin texture is the issue, use frequency separation.

Yep ! This did the job for me, I did not have to go to HSL Adjustment, the White Balance Adjustment itself were satisfactory for me.
