### TrueColor detection
Notcurses primarily loads control sequences from `terminfo(5)`, using the
database entry specified by the `TERM` environment variable. 24-bit "TrueColor"
color support (or at least the ability to specify 3 8-bit channels as arguments
to `setaf` and `setbf`) is indicated by the `rgb` terminfo capability. Many
terminals with RGB support do not advertise the `rgb` capability. If you
believe your terminal to support 24-bit TrueColor, this can be indicated by
exporting the `COLORTERM` environment variable as `truecolor` or `24bit`.
Note that some terminals accept a 24-bit specification, but map it down to
fewer colors.
TrueColor is always enabled for Kitty, Alacritty, Contour, and foot.
* If your terminal supports 3x8bit RGB color via `setaf` and `setbf` (most modern
terminals), but doesn't export the `rgb` terminfo capability, you can export
the `COLORTERM` environment variable as `truecolor` or `24bit`. Note that some
terminals accept a 24-bit specification, but map it down to fewer colors.
RGB is enabled whenever [Foot, Contour, WezTerm, or Kitty](TERMINALS.md) is identified.
