As for colors, my friends and I have been playing Dragon Age Inquisition multiplayer lately. The color palette for armors in that game is quite muted. And man, do the armors look like shit (models are awful too).
Goes to show that these things do have a certain subjectivity to them. I've always loved the color palette in DA:I, and in fact generally love how that game looks. I'm guessing it ultimately comes down to games like DA:I and TW3 adopting a more medieval look whereas BG3, based on D&D 5e artwork as has been discussed elsewhere, adopting a more renaissance look. I strongly dislike the renaissance look, even in the real world.
