How to Change Skin Tone in Photoshop
With Photoshop, it's super-easy to change or adjust a skin tone. The process uses some basic selection and color adjustment tools, and is a fun way to make a friend's face green or lessen the effects of overly strong, sometimes even orange, makeup.
This tutorial will work well with most versions of Photoshop, and can be mimicked almost exactly with programs like GIMP.
For this guide, I'll be using this image of President Trump:
You can use any one of the selection tools available in Photoshop, but for this guide, I'll be using the Magic Wand Tool. Select the tool, then change the tolerance to 35.
From there, it's time to start selecting. Hold the Shift key and select as much of the face as possible. If you select a part of the image you don't want, like the hair, hold the Alt key and click the are to deselect it.
Once you have the general area selected, you can lower the Magic Wand tolerance to fine-tune any areas you missed, or deselect any areas you don't want (like the eyes).
With the face selected, head to the menu bar to Image -> Adjustments -> Desaturate.
Now go to Image -> Adjustments -> Levels, then start with the furthest slider to the right and bring it to the left. Then the same with the middle slider. This will vary on a case-by-case basis, so you'll need to play around here.
All that's left to do now is adjust the color to your liking. Go to Image -> Adjustments -> Hue/Saturation and tick the option for Colorize.
Now that we added some color back, it's time to adjust the tone. Use the Hue, Saturation, and Lightness sliders to settle on the skin tone you want.
And there's your finished product. For a video reference, check out the guide below.
