Gooch cool to warm technical shading

Shade a mesh from a cool tone facing away from the light to a warm tone facing it, with a white Blinn highlight and darkened silhouettes, for technical illustration that keeps shape readable in shadow.

Limits to consider

Non-photorealistic. Shadows from other objects are not darkened (Gooch shading ignores cast shadows except in the highlight); environment ambient light adds a uniform term. Edge darkening is a facing-ratio approximation: flat faces seen edge-on darken entirely.
