What color value is skin tone?

Question

If I want to push skin tone in the Colour Board (Apple's rectangular version of the "colour wheel") in a colour adjustment, should I be pushing at 30 degrees?
The FCPX user manual says in "Vectorscope display options",
"Show/Hide Skin Tone Indicator: Shows or hides the diagonal line that represents the human skin tone chroma phase, which is between the yellow and red color bar targets."
It doesn't say if the skin tone indicator is exactly between yellow and red, i.e. pure orange, which would be 30 degrees, or just somewhere between red and yellow.
I found this in a Larry Jordan article,
"Regardless which race or ethnic group our actors are a part of, all of us have the same red blood under our skins. This line (skin tone indicator) represents the color of red blood under skin. In general, when you want to make skin tones look normal and believable, you want them within a couple of degrees of this line. Above the line leans ruddy, below the line leans sallow."
So, is the red blood under our skin pure orange, i.e. 30 degrees in the Colour Board, i.e. exactly mid way between red (zero degrees) and yellow (60 degrees), or is it some other value?

Many thanks for all your help.  I suppose I am trying to arrive at really nice cinematic looking skin tones, but with my Canon 550d and very limited knowledge of setting up shots and film making, pushing skin tone and playing with the colour board alone will not get me those appealing skin tones.  Attached are some interesting ones, but how to achieve them?  I need to keep learning, and perhaps have a good lot of cash for gear ..
