In the first image, note the obvious matching of the hues between the rocks and the shoes. The saturation also appears to be heavily edited, note its flat appearance on her face.
In the second image the rocks on the ground have been made to match the hue of the clothes despite being different in saturation and there's the typical magenta/cyan palette
In the third image the shadows are tinted blue while the midtones of the skin are orange and the highlights have been pushed into yellow-green. Also note that the hues of the jacket, pants and background have been matched. The more saturated orange-ish midtones match the hue of the shirt's yellow-orange.
In the fourth image the skintones have been matched with the jacket and oranges in the background. The rest of the background is significantly desaturated and the saturation is relatively flat on the face (but towards a higher value).
These are not results you can get from SOOC images and they have been modified purposefully. Unifying hues allows you to then more specifically oppose hues against one another. It's hard to create strong color contrast when you have blues spanning from violet-tinted to green-blue and reds from orange to magenta-red. I think it's also worth noting in this set of images how much the saturation between different parts of the images is controlled to create more contrast between and within the colors.
