Terminal - SSH as Root, No ANSI Colours

Different shells maybe? Different variables set for whichever shell you're using? Alias set up for the 'ls' command?

 

Its complicated. Here's a starter: http://net.tutsplus.com/tutorials/tools-and-tips/how-to-customize-your-command-prompt/

A shorter version: The mac terminal logs each user into that user's preferred shell. Options are "bash", "tcsh", "zsh" etc. The default is "bash". For each one of those shells, there exists a ".bashrc", ".tcshrc", ".zshrc" etc. file that tells the shell how to behave. These ".{something}rc" files are unique to each user account. In your case, whatever shell your root and non-root accounts are using on the server when you SSH into that server, those shells have different ".{something}rc" files that tells the two accounts to behave differently. How to fix it is not trivial if you're not familiar with all that MAY be listed in the ".{something}rc files. The simplest option that might work for you is to alias "ls" to "ls -G" for example. The link above has a much more detailed explanation of how you can modify your shell's behaviour with colour.
