RGB

# Feature Overview
Kind: RGB
Extendable: no
JSON based: no
JSON config: through vehicle/container config

RGB is a class/util from FCL!
It stores a single-int color value and a float alpha value.
Most if not all color based rendering in FVTM uses that.

In an FVTM config file, if something is expected to be RGB
it most likely will expect a HEX RGB, e.g. #00ff00.

Example: "Primary": "#4e4e4e" or "Secondary": "#353535"
