I'd guess it has something to do with the fact that human skin tones all fall within some range of orange. This is the reason behind the pervasive use of orange and teal color grading in TV and movies: it accentuates the contrast between people and the rest of the scene.

I came to the comment section to make this comment. I was surprised to find out that all skin is orange hue, even dark skinned people. This is one of the tricks of face detection algorithms, and it’s fun to take pictures of people and then extract the hue channel to see this in action. You can do it in any photo editing app by converting to HSV color space and then setting the S & V channels to 1.
