Actually, I'm pretty sure dragons fall into the same existence styling as fiends and celestials here - Just as a fiend who ceases to be evil also, at that time, ceases to be a fiend and is changed by it, and a celestial who ceases to be good is also changed physically by that shift: the same goes for dragon, if a little differently - metallics that lose their goodness tarnish and cease to be true metallics, and, similarly, a chromatic that genuinely becomes no longer evil in their essence undergoes a shift and will no longer resemble a chromatic.

I'm, er, not really sure where the new crystals from Fizban's fall into all of this...
