pwd alias causing infinite loop in UNIX (bash)

I have an alias, dir, which works fine using $(pwd) to show me the current directory I'm in:

alias dir='echo -e ${color1}jarvis: ${color2}you are currently in the ${color3}$(pwd)${color2} directory, sir.${NC}'

I would rather this alias be pwd, or have an identical one for pwd (so i can use dir or pwd to get the exact same response), but I seem to end up in an infinite loop everytime I try alias pwd=dir or 

alias pwd='echo -e ${color1}jarvis: ${color2}you are currently in the ${color3}$(pwd)${color2} directory, sir.${NC}'

any ideas?

In bash, the environment variable PWD is always kept current. pwd is the shell built-in you shadowed with your alias, and /bin/pwd is always around in case it's 1984.

alias pwd='echo -e ${color1}jarvis: ${color2}you are currently in the ${color3}$(\pwd)${color2} directory, sir.${NC}'

Backslash in \pwd avoids the alias.
