HUSL color space conversion

A color space conversion library that works with numpy. See http://husl-colors.org to learn about the HUSL color space.

Features

1. Fast conversion to RGB from HUSL and vice versa. Convert a 1080p image to HUSL in less than a second.
2. Seamless performance improvements with NumExpr, Cython, and OpenMP (whichever's available).
3. Flexible numpy arrays as inputs and outputs. Plays nicely with OpenCV, MoviePy, etc.

Installation

1. virtualenv env -p python3
2. source env/bin/activate
3. pip install numpy
4. (optional) pip install Cython (or NumExpr, but Cython is preferred)
5. pip install git+https://github.com/TadLeonard/husl-numpy.git

Basic usage

• to_rgb(hsl) Convert HUSL array to RGB integer array
• to_husl(rgb) Convert RGB integer array or grayscale float array to HUSL
• array
• to_hue(rgb) Convert RGB integer array or grayscale float array to array of
• hue values
