Sort out Color

[MarkOates]

Color class has undergone a lot of changes during the pre-alpha development cycle. There's Color, Color::color... there Color() methods which can't be used to create a color. It always seems to be confusing when it comes time to actually use it in development. Should review this (which will probably result in needing to update a lot of phantom dependencies and dependent project code and is probably why it has taken so long to actually address).
