Reminds me of that overwatch character with the yellow healing aura and the green speed aura. Just why?

Because his default coloring is green and yellow I'd guess

Yeah but the healing aura should be green and the speed one should be yellow

Electric element. Team Yellow vs Team Blue, FIGHT!

Nah this one is easy.

If it's green and sparkly, it's a good thing. If it's green and bubbly, it's a bad thing.

Not sure if this is more or less of a problem for people wtih red-green colorblindness.

On the one hand, it's harder to differentiate at all. On the other hand, it kind of removes that established expectation and keeps you in the habit of adapting.

Overlord the anome has a whole arc about the protagonist using his immense power and influence to have people start research on how to turn blue potions red.

There is (was?) an electric power provider in Germany by the name of Yellow. Their whole marketing was "electricity is yellow!"

It's true.

Rules are meant to be broken - apart from when they aren't.

You can change any aspect of the world any way you like, but only if doing that is critical to your universe and story.

Messing up without reason conventions that are well established is a dick move, unless the whole point of your work is to screw with people.

Bright red barrel of aircraft grade fuel.

Shoot it.

Spawns a leak.

//FPS players mind's implode//

Green means go.

Yellow means “Yello? I don’t got all day!”

And yellow means, uh, holy light, or something.
I ain't played no Overwatch, but I all but guarantee that's what it is.

Electricity is yellow.
Blue would be water.

What game would actually use blue?

what do you mean? electricity is purple

except the ones made from potatoes and cheese, those are just soup

Looking at you, "Dragon Age" Veilguard.

If you don't think soup is addicting, you haven't had soup.

Daggerfall!

How about this food is poison and snake bites heal?
