This is part of the Telnet protocol.

The Telnet protocol is documented in RFC 854.

The escape sequences used to specify colours are specific to the type
of terminal being used. You need to consult the terminfo entry
corresponding to the value of the TERM environment variable in order
to determine whether the terminal supports colour, and which sequences
it uses. See the terminfo(5) manpage for details. The simplest
approach is to use the ncurses library to handle the details.
