Kushiro Color Stop Shader is a material node setup for NPR and toon rendering in Blender. It allows users to create stepped color shading by specifying the number of color stops via a parameter, bypassing the need for a ColorRamp node. The shader supports custom base colors or textures.

The node group includes controls for noise between color stops, noise scale, noise roughness, and noise rotation angle. It is designed with a minimal node tree to facilitate user modifications. The shader is compatible with both EEVEE and Cycles, using a fake lighting setup for Cycles support.
