Purple: Magic??
Green: Life/death??
Red: Life/fire??
Blue: Magic/cold??
Honestly the only colour I don’t feel uncertain about is orange, that’s always bad.
Also on the topic of health potions, a great piece of advice I once heard was that if your players are in a foreign land, remove health potions. Give them health biscuits and watch them reconcile with God.
I’ve never made the link between that and gender before (linguistically), it seems obvious in hindsight.
