Where did they get thier names?

Dragon, Proton, ect where did these names come from? Are they specific to this forum: or is it the name of the paint color: or what??

Yep, those are the names that Isuzu gave to the different paint colors:
Astral Silver, Kaiser Silver, Foxfire Red, Proton Yellow, Victory White, Dragon Green, and of course the best color of all, Ebony Black.

And those are just the US-specific colors. The Japanese Domestic Market (or JDM for short) has a whole palette of colors available!
