I want the style to have a religious/astronomy/science type of look. Here is a little information about melanin.
The Molecule Melanin and how it is prevelant throught nature and the universe..
I have done some research on this molecule and it is rather interesting to say the least. It is found in all things animate and inanimate, and on our skins when it is produced, it protects us from harmful UV radiation and converts sunlight into vitamin d and internal energy or Chi. It is being used prevalently in Eyeware and being researched as a more effect sunscreen and has been noted as an amorphous semi-conductor in a 1972 research paper. I am sure more research has been done on this molecule since then.
The Sun has always been seen as the provider of light, but it is actually the water and melanins in the atmosphere which create the energies we see as light and feel as heat. The sun and space and the universe are replications of the microcosm in us and all things on a cellular level, so the sun would be a large dark melanin molecule in an organic universe. The spaces in and between the sun, planets, stars, and in and between alll living things on any earthlike planet would be composed of melanin (dark matter) and water, since both are receivers, storers, converters and emitters of all energies.
