[edit] Detection
There is no universal standard for the detection or negotiation of ANSI color support. The following generic methods exist:
- By using the TTYPE TELNET option and checking for a terminal emulator or mud client known to support ANSI colors, such as xterm.
- By using the TTYPE TELNET option and checking for the -color suffix, such as xterm-color.
- By using the TTYPE TELNET option and checking for the MTTS extension to detect ANSI color support.
- By using the MSDP TELNET option and checking if the client set the ANSI_COLORS variable to 1.
Note that most muds either assume the client supports ANSI color, or ask the user during login if they wish to use color.
