Thinking About Color in Shadows

It's been a couple of very busy weeks with the completion of the new studio, moving into the space, and also gearing up to start work on a large commission painting. I haven't had much time in front of the easel, or in front of the computer to edit videos, so I thought I would record a brief discussion on thinking about color in shadows, specifically while painting flesh-tones. 

You'll need to watch this video full screen to see my cursor (this was also partly an experiment in recording my computer screen).

I hope you find this information useful. Please leave your questions in the comments.

Also, I near the beginning of the video I mistakenly refer to the local color of the grass as yellow. Obviously, it's green. 

Happy Painting!

Update: I just finished painting the younger sister's head, and the attached image shows how I approached some of the issues I talked about in the video: Low chroma light on the bottom of the chin reflected off the gray shirt, pink light under the eyebrow ridge reflected off the older sister's shorts, warm (higher chroma red/orange) shadows around the eyes, inside the ear,  and where the neck turns under the hair (light reflecting around off of other flesh-tones), and very high chroma red/orange light where the sunlight is passing through the skin on the ears, the cast shadow from the forehead on the bridge of the nose, and inside the nostril.
