ELI5:Why most of the games show posion as in green colour? Is it true?

Whenever i played lara croft, assassin creed, far cry etc. i've seen examples of it. I wonder if it is relevant or random stuff?

As mentioned before, the colour green is associated with sickness. Many people may also think about Chlorine when they hear "poison" - which was used for its poisonous properties during World War 1, and is a green gas. The substances used as rat poisons ages ago were also green.

Modern poisons aren't necessarily green at all, they are usually colourless (poisons aren't very effective if they look obvious).
