.profile and .zshrc both look for their .$HOSTNAME
brethren.
put shell agnostic customisations in .profile.$HOSTNAME
and settings
relating to zsh specifically in .zshrc.$HOSTNAME
.
I now use the zsh colors hax, so you just need
ie, SHELL_COLOR=$PR_BRIGHT_YELLOW```
in .profile.$HOSTNAME
However, if you use my tmux config you will likely want to export
```TMUX_SHELL_COLOR=color``` in the same file, eg
```export TMUX_SHELL_COLOR=magenta,bold``` to color the hostname in tmux to
match your zsh prompt
