I really like, at least, the idea of the inverted core colors. I also like the look of it. I can't tell exactly why - although, to be fair, Bushy was building an effect based off of reference, which is something that has been kind of lacking in the lightsaber department for years. The effect has been much more "we, as us, think this looks better," and have acclimated our eyes to that look. And I like that look too. But something about the inverted core colors looks old school and optical, it feels more grounded, to me. The bright perfect white cores do have a very "After Effects in the 2000s" feel to them, and Bushy's don't. I don't like the inverted core colors substantially more than the glow-core colors, but I do like them. I think the inverted colors are a bit too dark, if it was a little less obviously-not-white, I think I'd be even more into it. Perhaps more than the established AE-2000 look. Or maybe I'm just refreshed to see something new. EDIT: And yeah, I really wanna see this in motion. Someone give this guy a clip and a core render he can do his color stuff to.
