Color string in terminal in zsh

I'm trying to convert this string that I had in .bash_profile

PS1="\e[37;1m$ [\e[0m]"

to an equivalent string in .zprofile in zsh. I've read the guide in

wiki.archlinux.org/index.php/Zsh

but I actually didn't manage to understand the new syntax to color my terminal and, in my case, show the full path where I am actually working. I understand it's a trivial questions but also looking at related post I didn't manage to fix my issue. Any hint would be more than welcome :)

Thanks
