See the discussion thread here: https://lists.gnu.org/archive/html/bug-ncurses/2013-10/msg00007.html Detection There's no reliable way, and ncurses/terminfo's maintainer expressed he has= no intent on introducing support. S-Lang author added a check for $COLORTERM containing either "truecolor" or "24bit" (case sensitive). In turn, VTE, Konsole and iTerm2 set this variable to "truecolor" (it's been there in VTE= for a while, it's relatively new and maybe still git-only in Konsole and iTerm2= ). This is obviously not a reliable method, and is not forwarded via sudo, ssh etc. However, whenever it errs, it errs on the safe side: does not advertise support whereas it's actually supported. App developers can freely choose to check for this same variable, or introduce their own method (e.g. an option= in their config file), whichever matches better the overall design of the given app. Checking $COLORTERM is recommended though, since that would lead to a = more unique desktop experience where the user has to set one variable only and it takes effect across all the apps, rather than something separately for each app. Here are terminals discussions: Now supporting truecolour st (from suckless) [delimeter: semicolon] - http://lists.suckless.org/dev/1307/16688.html konsole [delimeter: colon, semicolon] - https://bugs.kde.org/show_bug.cgi?id=3D107487 iterm2 [delimeter: colon, semicolon] - since v3 version qterminal [delimeter: semicolon] - https://github.com/qterminal/qterminal/issues/78 alacritty [delimeter: semicolon] - written in Rust kitty [delimeter: semicolon] - uses OpenGL cool-retro-term [delimeter: semicolon] Termux [delimeter: semicolon] - Android platform Black Screen [delimeter: semicolon] - crossplatform, HTML/CSS/JS-based Hyper.app [delimeter: semicolon] - crossplatform, HTML/CSS/JS-based (Electron) hterm - HTML/CSS/JS-based (ChromeOS) Tera Term [delimeter: colon, semicolon] - Windows platform ConEmu [delimeter: semicolon] - Windows platform FinalTerm [delimeter: semicolon] - abandoned, iTerm2 borrowing it's ide= as and features.
