Six Forgotten Warriors Chapter 2: Unclaimed Legacy - S5-E3
Silver Sable: I am not a criminal. I am merely a professional for hire.
Spider-Man: Which means you just work for whichever creep pays the most. I think I prefer these guys over here. Their dishonesty is more honest.





Answer: I believe it was just a way to try and show the suit is "oily" or reflective. It also helps define the character's features since otherwise, he'd just be a flat black color. It's similar to how the black suit Spidey had blue outlines. (I don't know why they chose a pink/red color... maybe because red is associated with power/fire/war, so it's a more "evil" color?)
