Palette Grid is a tool for creating and managing palette-based textures directly within Blender. It enables the generation of custom palette textures using flat color strips and gradients without requiring external image editing software. Users can design color layouts and adjust gradient stops in real time, with all changes syncing immediately to the active texture file. An image editor overlay provides visual selection outlines and hover highlights to interact with the palette directly.

The addon simplifies the UV mapping process specific to palette texturing workflows. It provides automated one-click UV snapping to assign selected geometry faces to specific color strips, generating UVs automatically if none exist. Additional mapping features include viewport projection, distance-based radial gradients calculated from the 3D cursor, and shape detection that applies gradients along drawn paths or shapes on the mesh surface.
