Description
Vertex Color Toolkit for Blender
A powerful addon for procedural vertex color assignment in Blender 4.0+
Vertex Color Toolkit gives you complete control over how colors are assigned to your meshes. Whether you need gradients, patterns, or precise color placement, this modular pipeline makes complex vertex coloring simple.
How It Works
The toolkit uses a four-stage pipeline:
Collect → Sort → Transform → Assign
Each stage is fully customizable, giving you thousands of possible combinations.
Collectors
Control how geometry is grouped before coloring:
- Per Face – Color each face individually
- Per Vertex – Color each vertex independently
- Object – Treat entire object as one group
- Shell – Group by connected geometry islands
- UV Shell – Group by UV islands
Sorters
Determine the order colors are applied:
| Sorter | Description |
|---|---|
| Position | Sort along X, Y, or Z axis |
| Conical | Radial angle around an axis (spiral effects) |
| Cylindrical | Distance from a central axis |
| Directional | Based on surface normal direction |
| Distance to Object | Proximity to a target object |
| Proximity to Path | Distance along a curve |
| Island Perimeter | Distance from boundary edges |
| UV Position | Sort by U or V coordinates |
| Bounding Box / Volume | Sort by object size |
| Hierarchy | Parent-child depth |
| Name | Alphabetical by object name |
| Random | Randomized with seed control |
Transformers
Modify the sort values before color assignment:
- Easing – 27 easing curves (cubic, elastic, bounce, back, etc.)
- Chunker – Create discrete color bands/steps
- Pattern – Repeating stripe sequences (e.g., “1,3,2”)
Assigners
Choose how colors are applied:
- Solid Color – Single uniform color
- Gradient – Smooth blend between two colors
- Color List – Cycle through multiple custom colors
Additional Features
- Noise Overlay – Add variation with adjustable scale, frequency, and phase
- Channel Masking – Write to specific RGBA channels
- Normals to Color – Convert mesh normals to vertex colors (XYZ → RGB)
- Custom Color Attribute Names – Organize multiple color layers
- Reverse & Seed Controls – Fine-tune your results
Requirements
- Blender 4.0 or newer
Installation
- After download the zip file and drag-n-drop into the Blender interface and enjoy!
