There's similar story to urxvtcd which is my nickname here, haha. They have an entry on rxvt:

Rob Nation's fork of the X11 Virtual Terminal; originally "Robert's" xvt, later "our" xvt.

Then they added "u" for unicode support. And then urxvt can run a daemon to which clients connect for faster startup or something, so we have urxvtc and urxvtd, and finally there was a script on some distro I used which checked for a daemon, run it if it not existed, and then run client, so urxvtcd.

Could have made one with color support included in the name too, like urxvtcd256.
