Had a slight change on mind, I'm sticking to Sherlock Holmes as my original text. Instead, I'm using fantasy as a genre because although it's a good idea in theory it would be difficult (and a lot of extra work) to make a script and then incorporate the elements of a daemon into the scenery.
My second genre will be the Victorian era which, granted, is where the story is set. However it's my favourite era and generally more linked into the script. So, I have been looking at Victorian interiors, which although some-what relevant isn't where the scene is set, which is a chemical lab. Thus, I had a search through google and came up with a couple of interesting images. Also I'm going to watch 'Frankenstein' and have a look at the lab in the movie.
Also, I had a look at the '09 SH movie; theres a scene where they go into the "ginger midget's" lab. There are lots of textures and colours there, as well as a lot of materials they would have used in that particular era.
Finally, I am looking at horror, which to my own horror, everyone seems to be doing. Sucks.
Disregarding this annoying fact, I have researched Henry Fuseli whom is a romanic artist. However, I'm focusing on the concept which a person's ideas, personality and dreams taking a physical manifestation in the image.
This has influenced how the scene is portrayed to the audience, a room which has the aspects of a chemical lab but also manifestations of Holmes' personality visible only to the audience. There are many views on Holmes' personality, but giving the audience an insight into his mind will give a clearer image of the sort of man he is. For example, I considered objects such as needles, cluttered books, broken violins, tobacco, pipes, music sheets or notes; perhaps carved or etched into surfaces such as tables/chairs/walls/floor inspired by the image below:
Also flowers, dead pressed flowers which have a meaning such as lilies; the flower of death. Death is part of Holmes' work, the cases he finds most interesting. Also flowers are a key feature in many gothic artwork, and this could not only be a key feature of the scene but also the costumes too.
Colour is also a key feature, and so browns, pale green, and earthy reds would be a good colour scheme and one which links back to Victorian colours.
