I saw a trailer for Spooks recently where they had to stop a deadly toxin from being released somewhere with lots of people.

You could tell it was deadly, as when they showed the test-tube filled with toxin, it was a evil shade of bright green [rofl]

Whilst that might seem hilarious, often very toxic chemicals are deliberately coloured this way to warn people that they're not for pouring on your beans on toast...
