Ember: Nightshift / Redshift safe color palettes
Summary
Ember is a GitHub-hosted project that provides redshift-safe color palettes for terminals, charts, and UI. It focuses on preserving color distinguishability under warm-filter transforms with four palette families and accompanying artifacts for various platforms, including terminal themes and plotting assets. The project explains the underlying perceptual color model, release criteria, and how to integrate the palettes into common tools.
