Overview

About

Maintained by Yann CohenFirst published 2026-03-042 releasesCRAN page ↗GitHub ↗

Provides a comprehensive 'API' for colour conversion between popular colour spaces ('RGB', 'HSL', 'OKLab', 'OKLch', 'hex', and named colours) along with clean, modern 'CSS' Color Level 4 syntax output. Integrates seamlessly into 'Shiny' and 'Quarto' workflows. Includes nearest colour name lookup powered by a curated database of over 30,000 colour names. 'OKLab'/'OKLCh' colour spaces are described in Ottosson (2020) https://bottosson.github.io/posts/oklab/. 'CSS' Color Level 4 syntax follows the W3C specification https://www.w3.org/TR/css-color-4/.

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \

For install.packages() integration in R, also: sudo dnf install R-CoprManager
