Pretty PS1 colors and brackets

I think this looks reasonably good on dark and bright backgrounds, without looking aggressive on either:

(sorry for the bikeshedding :wink:)

Probably needs to be PS1="\033[1;35m\342\246\227${VIRTUAL_ENV}\342\246\230\033[0m ${PS1-}" to reset colors at the end otherwise it ruins up rest of prompt. Thing is it does not work on macOS because ZSH handles colors differently so will need to have if/else/fi block to check for it.

Would suggest this change, zsh is quite verbose so you can see intention there:

_OLD_ENVIRONMENT_PS1="${PS1-}"
if [ -n "${ZSH_VERSION-}" ] ; then
    open=$'\U2997' closed=$'\U2998'
    PS1="%{$fg[magenta]%}${open}${VIRTUAL_ENV}${closed}%{$reset_color%} ${PS1-}"
else
    PS1="\033[1;35m\342\246\227${VIRTUAL_ENV}\342\246\230\033[0m ${PS1-}"
fi
export PS1

\033[0m resets all attributes. \033[39m only reset the foreground color. Since we are only changing the foreground color I thought it's sensible to only reset that attribute. (But in the end I don't really care. :D Just wanted to explain why I used \033[39m instead of \033[0m.)
