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.

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

Still heals HP. Definitely a health soup.

Blue-white lightning icons/symbols are quite common, I would think. Slay the Spire comes to mind:  Then again, there are some yellow ones, too: 

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

Also you need to consistently break conventions once you do it or you really screw with people and make a shitty world.

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.

The pulp is from fruit, right? *The pulp is from fruit, right!?*

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. ‍️

Toss a lighted match into the growing puddle. Match goes out.

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

Idk, he's a Brazilian roller-blading sports-loving DJ... I think most likely scenario is he was green and yellow based on the Brazilian flag, green means "go", and there was only one other color left for "heal", so it's yellow.

FFXIV the stack markers are close to orange... and long time ago it had Bard having a fire circle that damaged enemies but not allies, yet the tanks thought it was bad and would drag enemies out of it. Probably why they removed that one.

My world is shattered. I think I was thinking of Mercy. But I guess her angelic yellow beam is more God's Wrath than it is Pastor Cures Your Back Pain anyway.

Or radioactiv acid!

Oooh i think his name is Lucio. These colours, from what i know, depend on which skin you have on

Then you are an undead

Yeah, I meant his default skin, sowwy

I love the possibility of having a red/green colorblind character and having to roll to hopefully pick the right potion when they both health potion and poison in their bag.

In Overwatch, healing is consistently represented by the color yellow. Making Lucio's speed aura yellow and healing aura green would be visually confusing
