Technicolor Toxin



In Real Life, poison is usually detected and identified thanks to its bitter taste and/or smell. But how can we identify a poison as such in works like anime or video games, where taste and smell aren't an option?

Of course, the color itself!

Eastern media tend to portray poisonous substances in a dark purple color, usually bubbling. In Western media, Sickly Green is more common (because of the former popularity of Arsenates, which really are fluorescent green). There are also other works from both sides of the Atlantic showing poisons and venoms of various other colors. Bonus Points if it's shown melting stone and steaming foul vapors.

Thanks to these distinctive colors, the audience can instantly perceive whether a substance is toxic or not. This is a bit of Truth in Television, as shown below.

Seen often paired with Poisoned Weapons, Poisonous Person and Perfect Poison. See also Sickly Green Glow and Purple Is the New Black.

 * In A Song of Ice and Fire, when, it's strongly implied that this was the work of the Tyrells, specifically Cool Old Lady Olenna, who would have taken a poisonous stone disguised as an amethyst out of Sansa's jeweled hair net and dropped it in his cup of wine. One indication of this is that when Tyrion gets wine poured over his head, it's described as a "red torrent," but when he picks up the chalice after it's been refilled and drunk from, the remaining wine is purple.
