I'm not a fan of the step rails (just my opinion) but if you don't want them to stand out the go with black. But you do have enough chrome accents to be able to go with stainless. My dad has some stainless rails on his truck & just about every dealer installed chrome accent available on a white Z71 & as much as I don't like chrome (also) his truck looks good. GO STAINLESS! Have fun truck looks good.
