It’s important to keep in mind that colors aren’t isolated, their surroundings affect how we perceive them. In the case of skin, it’s usually surrounded by fabric, sky, and grass, all of which influence its color through reflective light and overall color perception.
A general rule of thumb is that skin tends to be low in saturation and light in value when hit directly by light. It becomes more reddish when backlit (blood and skin is translucent). Fabric, on the other hand, tends to be higher in saturation and mid in value. This contrast helps clearly distinguish skin from drapery.
Here’s an example from some time ago, a great work by an anon who was struggling with this. Many of these questions can be answered by studying the masters.

great anon! I think hinting the sternomastoid will give a 3d feel to the neck.

>Dunno why I get "blind" to this stuff when drawing.
whats funny to me is that we often forget that we have a life model 24/7 available that we can touch and move as we desire.
