RE: Does the color of your scales have meaning?
No, not that I'm aware of, and sort of. Let me elaborate:
Dragon 1: Black and green shades, as far as I know just camouflage in our forest environment. This dragon was of lower intelligence, so did not have a complex society or concepts like "elements" or possibly even language as we know it.
Dragon 2: (actually hide, not scales, or if they were scales then they were very fine) Silver; others of the same species were metallic pale yellowish green and metallic pale orange. I don't have any specific memories of this having societal meaning (even as much as hair color does to humans, much less any specific conceptual associations or societal roles), but it is probably more accurate to say "I don't know" than "No".
Dragon 3: Nonphysical (although capable of "condensing" into a physical state). Colored like space and stars because that's what they are "of". So this one yes, the coloration does mean something about the dragon.
Formerly known as Eshari.
