I agree with liking more fanfare in the costume, @BatJamags. Those two were standouts for those reasons. With a less pronounced Bat symbol on the chest plate, it also seems like a “yeah, it’s Batman - you know him already” kind of move. The White Knight suit is two-tone black and gray.
I like Bruce’s reasoning for choosing black more often, as it blends with the shadows (he works at night), strikes fear into his foes, and pairs well with the naturally dark Gotham streets. A blue or yellow pop of highlight is a really nice touch that I have always loved as well.
