Tempus Themes project
Accessible themes for terminals and text editors
Tempus is a collection of themes for Vim, text editors, and terminal emulators that are compliant at the very least with the WCAG AA accessibility standard for colour contrast between background and foreground values. This stands for a contrast ratio >= 4.5:1. Items of the Tempus themes collection are either light or dark, while some of them comply with the even higher accessibility standard of WCAG AAA, else a contrast ratio >= 7:1.
The code and sample screenshots are on their GitLab repository: https://gitlab.com/protesilaos/tempus-themes.
