prettypretty python

Description:

Prettypretty is a Rust library with optional Python integration that brings 2020s color science to 1970s terminals for building awesome terminal user interfaces (TUIs). The intended benefits are twofold:

• You get to design and build the TUI with all the expressivity and convenience of high-resolution color and color spaces, including the perceptually uniform Oklab whether in Cartesian or polar form, with original or revised lightness.
• Prettypretty takes care of reconciling the intended appearance with the capabilities of the terminal, the current runtime context including light or dark mode, and the user's preferences, whether they lean FORCE_COLOR or NO_COLOR.

To make that possible, prettypretty provides simple abstractions for terminal and high-resolution colors alike, facilitates seamless conversion between them and common color spaces, and implements state-of-the-art algorithms for gamut-mapping, color interpolation, perceptual contrast, as well as its own hue- and lightness-based downsampling for optimal selection of ANSI colors.
