"There are no 'rules' for fantasy"

Wrong. To write good Fantasy (of SciFi), you have to go through a process called "World Building" where you lay down the rules of your world. Properly done, the amount of World Building exceeds the actual works by far. It is absolutely necessary to create a core of inner logic to the story. You are not bound by the rules of our world, yes, but you are bound by the rule of consistency. If you violate those, you automatically write crap Fantasy (or SciFi).

Funny, though, that e.g. many literature teachers / professors don't even know about the idea of World Building.

The old TSR/SSI game Unlimited Adventures had randomized potion colors. It's also how I learned that khaki is not pronounced 'kahiki' when trying to explain what was going on to someone (I knew khakis as a type of trouser not a color).

Edit: or maybe I'm thinking of another gold-box game if that one didn't have some random generation. Hrm.

Why should your fantasy game be limited by something like "health". Whether you die should be based on vibes.

Nethack (and derivatives) is pretty much the only game I know of where the health potions may or may not be red.

And I guess Dark Souls... It's more of an orange than a red. But maybe that's just the color of the flask. Idk what the substance inside looks like. 🤷🏻‍♂️

Bright red barrel of aircraft grade fuel.

Shoot it.

Spawns a leak.

Similarly to how paprika chips come in blue bags and salted chips come in red bags. Anything else is heresy. Unless you live right across the border, where it's exactly the opposite.

Big glowy green area? Could be a healing aura, could be poison. Good luck!

My health potions are red, also, pulp free is not an option. >:)

I used yellow for health to avoid red/green colourblind issues

I hate dragons. Controversial take but like just come up with some other mystical creatures! have some fun with it! if rather interact with a pink unicorn plushie than fight another dragon

Electric element. Team Yellow vs Team Blue, FIGHT!

How about Oblivion where every potion, including drugs, are red?

I color code all my info. (..) Green means go, so I know to go ahead and shut up about it. Orange, means orange you glad you didn’t bring it up. Most colors mean don’t say it.
