A Blender utility for creating, converting, sampling, refining, and managing Color Ramp workflows.
Part of the DRH Add-ons ecosystem — Blender tools, updates, and releases.
DRH - Color Ramp Studio helps Blender users build, sample, convert, organize, and refine Color Ramp setups more efficiently.
This repository is the central public hub for support, documentation, issue tracking, compatibility feedback, and community validation before marketplace release.

DRH - Color Ramp Studio is a Blender workflow utility designed to make Color Ramp creation, editing, conversion, sampling, and reuse easier across visual workflows.
It is intended for users who work with materials, shaders, procedural textures, Geometry Nodes, compositing, look development, gradients, palettes, and color-driven effects.
Instead of rebuilding ramps manually or losing useful color setups inside isolated node trees, DRH - Color Ramp Studio helps turn Color Ramp workflows into a more reusable, editable, and organized process.

DRH - Color Ramp Studio helps you create, sample, convert, refine, restore, and transfer Color Ramp setups inside Blender.
It is not only a simple gradient preset tool. It is designed as a workflow helper for artists and technical users who rely on Color Ramps for materials, procedural effects, masks, stylized looks, terrain, particles, shader variation, and node-based color control.
Use it to:
- Create Color Ramp setups faster
- Generate useful ramp variations
- Sample colors from image-based sources
- Convert color information into usable ramps
- Refine ramp stops and color distribution
- Restore or reuse previous ramp setups
- Transfer Color Ramp data across supported workflows
- Improve shader, material, and procedural color workflows
- Image-to-ramp palette extraction for faster look development
- Non-destructive conversion of native ramps into editable advanced workflows
- Copy, paste, and transfer tools for reusing ramps across node setups
- Screen color sampling for palette capture directly from visual references
- Ramp cleanup and refinement tools for positions, colors, alpha, and distribution
- Restore tools for safe round-tripping after conversion
- Preset browser with previews, search, and color-family filtering
- Works across Shader Editor, Geometry Nodes, and Compositor
