With my DAW of choice, they provide a color scheme edit and save option, and users would post their creations on the unofficial support forum for the DAW software. Some even were chosen to be included in upcoming releases of the software. I don't have alot of time for these things, but I found one particular user-contributed scheme that really resonated with me and just used that one.

It is pretty amazing how a color scheme can change one's view of the software. Part of the whole 'perceived quality' aspect of a product.
