Some damn nice bling.
I remember seeing that concept art of the black and gold Kylo helmet even before we saw any official image of Kylo Ren. Thought it was really cool.
I think if you change the silver to gold, you could do it in all three films. Then keep the red cracks red.
Oh I’d hate to lose the silver. I just think the gold visor might be a clearer way to get across the “regal” idea you had for TROS specifically, even if it wouldn’t make that much sense that it was changed.
