Changing the prompt style of a virtualenv instance with zsh

Question

I would like the change my zsh prompt style for every virtualenv instances that I use or create. My actual prompt is like this:

declare PS1="%{$fg[magenta]%}%n%{$reset_color%} at %{$fg[yellow]%}%m%{$reset_color%} in %{$fg_bold[green]%}%3~%{$reset_color%}"

When I activate a virtualenv it just adds some information before the prompt:

(the name of my venv)my_prompt

Do you know a way to change the colors or styles?

If you use virtualenvwrapper you can use its hooks to do this.
