I installed tf and I highly doubt that there is any other way to run tf
then in a terminal window, because the program is just text.
No fancy gtk or qt frontend.
I don't see any color option in the arguments either:
$ tf --help
tf: illegal option -- -
Usage: tf [-L<dir>] [-f[<file>]] [-c<cmd>] [-nlq] [<world>]
tf [-L<dir>] [-f[<file>]] [-c<cmd>] <host> <port>
-L<dir> use <dir> as library directory (%TFLIBDIR)
-f don't load personal config file (.tfrc)
-f<file> load <file> instead of config file
-c<cmd> execute <cmd> after loading config file
-n no automatic first connection
-l no automatic login/password
-q quiet login
-v no automatic visual mode
<host> hostname or IP address
<port> port number or name
<world> connect to <world> defined by addworld()
So, you'll have to live with the fact it's a program that has to be run inside a terminal without color.
