Not everyone would agree with that assessment, but if you personally like colours.. improperly spelt ports like
sysutils/colorls exist, and you could modify your PS1 environment variable to escape some things with colours.
As I said, you would have to modify wscons... that console terminal framework.. there are no settings or options that can do what you want, you will need to be able to read/write & comprehend the C language to accomplish your goal.
