In Agatha Christie’s Cat Among the Pigeons there is this whole thing about precious jewels and the pull, comparable to madness, that they have on people. The rocks in this story are a giant pile of emeralds and I will always remember the ending, where one of the characters gets to keep a single emerald as a sort of kindness on Poirot’s part and there is a great line about how all sorts of jewels are beautiful, but emeralds suit her the most, because green is the colour of magic. :B And it totally is. Green is also associated with water in western culture, especially deep, mysterious water. It is not a coincidence that the Hollywood remake of Dark Water is full of a murky, sickly, dangerous green:
Incidentally, both the original Japanese and re-made Hollywood versions of Dark Water are great movies, and amazing haunted house stories. Really atmospheric and gloomy and sad.
In the early years of the 19th century, green was dangerous, because green paint mixtures and green dyes were made using arsenic as a main ingredient, which provided the paint with a rich, emerald colour, but then also provided people with death. Green is obviously no longer the silent killer it once was, so thankfully for all of us, we can now enjoy the following photos in the privacy of our own homes and underwear, even if our houses don’t look like this themselves.
