Gooch cool to warm technical shading
In your harnessGodot shaderMIT
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.
What it takes and gives
- Shader type
- spatial
- Parameters
- surface_color (vec4 = 0.72, 0.66, 0.58, 1), cool_color (vec4 = 0.08, 0.16, 0.55, 1), warm_color (vec4 = 0.62, 0.48, 0.08, 1), cool_mix (float = 0.25), warm_mix (float = 0.5), highlight_strength (float = 0.7), shininess (float = 48), edge_darkening (float = 0.7) and 1 more
- Result
- A mesh in blue to yellow shading with a white highlight and darkened outline band.

Limits. 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.
