The Modus themes are designed for accessible readability. They conform with the highest standard for color contrast between any given combination of background and foreground values. This corresponds to the WCAG AAA standard, which specifies a minimum rate of distance in relative luminance of 7:1.
Modus Operandi (modus-operandi
) is a light theme, while Modus Vivendi
(modus-vivendi
) is dark. Each theme’s color palette is designed to meet
the needs of the numerous interfaces that are possible in the Emacs
computing environment.

To ensure that users have a consistently accessible experience, the themes strive to achieve as close to full face coverage as possible (Face coverage).

Starting with version 0.12.0 and onwards, the themes are built into GNU Emacs.
