bash back to olden days

for some reason i don't like coloured text in tty. Linux, by defaut sets weird colour for any display in tty. For example tar files will be listed ( as part of ls output) as red... weird.. but i would love to see it in old unix style.
here is how you could do it.

a) copy /etc/DIR_COLORS to /home/urloginName/.dir_colours
b) change "COLOR tty" to "COLOR none"
