What is it?

openlut is a practical color management library/tool that aims to simplify and unify all the various methods of making accurate color transformations.

Supported transforms include:

  • 1D and 3D LUTs
  • Color Matrices
  • Gamma Function
  • CDL Transform

It's built on my own color pipeline needs - I needed a simple but close-to-the-math solutions that dealt not with images, but with float arrays.

As a tool, its main feature is that it's exceptionally easy to import, transform, and then save not only images, but also transforms.


Docs can be found at They're a work in progress for now (ColMap is 100% documented).


  1. Check Versions: Ensure you have Python 3.5+ installed.

  2. Get System Dependencies - needing to do this is an unfortunate side effect of PyPi.

    • On Debian/Ubuntu: sudo apt-get install python3-pip gcc libmagickwand-dev
    • On Mac: brew install python3 gcc imagemagick
  3. Ensure Core Python Packages are Up To Date: Simply run pip3 install --user -U pip setuptools wheel to do so.

  4. Install OpenLUT: Run pip3 install --user openlut.

    • This may take awhile, as it must compile the C++ Extension.


  1. Clone the Repository: This is easy enough to do - just run git clone

  2. Compile Openlut: Again, very easy - just run ./build <TARGET>, where <TARGET> is some build target as listed in ./build -l.


Pip doesn't work: If Python is installed, but pip won't run, try running curl | python3

Doesn't work on Windows: I'm unsure of how pip compiles C Extensions on Windows, and have little willpower to investigate. If you need Windows support, PM me and I'll see what I can do about it.

Something's broken...: There may be several bugs. If you start an Issue, then I can investigate.
