A cross-platform library for determining the terminal's background and foreground color.
It answers the question «Is this terminal dark or light?».
Works in all major terminals including Windows Terminal (starting with v1.22).
use terminal_colorsaurus::{color_scheme, QueryOptions, ColorScheme};
match color_scheme(QueryOptions::default()).unwrap() {
ColorScheme::Dark => { /* ... */ },
ColorScheme::Light => { /* ... */ },
}This crate borrows ideas from many other projects. This list is by no means exhaustive.
- xterm-query: Use
mioto wait for the terminal's response with a timeout. - termbg: Lists a lot of terminals which served as a good starting point for me to test terminals as well.
- macOS doesn't like polling /dev/tty by Nathan Craddock
- This excellent answer on Stack Overflow for determining the perceived lightness of a color.
- This comment in the Terminal WG for the
DA1trick to easily detect terminals that don't support querying the colors withOSC 10/OSC 11.
