I remember being really unsure if I liked the way they changed the characters' irises, when we first saw them in the Volume 2 Production Diaries, especially since the gradiant color in Volume 1 made RWBY's "anime" style look a little different from most anime. Anime tend to have the irises be two-tone and generally don't use a gradient, which makes sense. It's easier to use gradients on stuff in 3D animation than 2D.

As for knowing the terms, I'm not sure if there's a more accurate term than two-tone, but that's the term I've heard and seen being used for stuff like that.
