About:
Lutgen is a high-performance command-line tool that generates and applies interpolated Look-Up Tables (LUTs) for color grading and palette manipulation. It leverages parallel processing for rapid color transformation, enabling developers and designers to quickly apply complex color schemes to images or generate custom LUTs for video and photo editing software.
Key Features:
  • Blazingly fast generation using parallel processing
  • Supports standard 3D LUT formats (.cube, .png)
  • Interpolated color transformations for smooth gradients
  • Simple CLI interface for batch processing
Use Cases:
  • Generating custom color grading LUTs for video/photo editing
  • Applying consistent color palettes across application assets
  • Automating color theme generation for UI/UX design projects
Alternatives:
  • ImageMagick – General-purpose image manipulation; Lutgen is specialized and faster for LUT generation.
  • OpenColorIO – Comprehensive color management framework; Lutgen is a lightweight CLI alternative.
