I'm more of a fan having Batman's suit in blacks & greys. The colors like blues & yellows are often more traditional but certain colors don't read the same way in different visual mediums. In film, i firmly believe black & (with or without) grey are the only way to go to let Bats maintain his badass status. While in comics or other non-cinematic pieces of art, can get away with some color. I've been playing around with digital colors so i felt the need to go against my usual vision for his suit & went with some color but met my preference halfway by using the blue as sort of a highlight on the black cape & cowl with a grey body suit so i could keep him a 'Dark Knight'.
Oh yeah, & Catwoman's in there too ;)
