How Do I Mix Shadows?

I feel like if you could just bottle all the times that an artist has thought like how did I mix that? Yes. That's a lot of times. As long as you match the value relationships that you're observing before you and your subject, you can paint it any color you want. You totally off the hook. Color gets all the credit. Value does all the work. So squint, you don't even have to think about color, but you do have to make a decision about how you're going to approach that.
