warm/cool colors You say that shadow color is based on sky color... If you have a warm light are you taking the same color and just cooling it down slightly by adding a cooler color, just very modestly changing the color slightly cooler? I guess the real question is, what's the point of using the concept for warmer and cooler colors?
It helps create depth? It helps in terms of realism, but how?

Reply color, color, who got the color...
I don't think you have it quite right. Shadow color IS based on sky color outside, regardless of what is warm and what is cool. Usually the sky is cool so the use of warm light and cool shadows usually works.
Look at it this way though, without reflected light and ambient "sky" light all shadows of the sun would be pitch black. What you actually see in the shadow is, first any reflected light from the primary light source, which is usually the sun outside but not always, then the light that the sky emits. Since the sky's light is not directional, other than vertically, it fills in the shadows and tints them with its color--whatever it is, cool or warm.
So, the light or sun color, theoretically, has nothing to do with the shadow color. In practice though, the sky and the sun do relate because the sun color does affect the sky color.
Now, when in comes to showing distance, the light and the shadow colors or "chroma" ranges do grow closer together and the value, or the contrast between the two lessen. How much depends on how much "air" the viewer sees. The more haze the faster that happens.
Hope this helps.
