Little known fact: For night-time camouflage you actually don't want jet-black, you want some black with mostly dark and drab greens, blues, greys and browns. The reason why is that black can still be easily picked up by the human eye in dim light, but the dark and drab colors mess with the way human eyes handle dim light, making it much harder to clearly see or pick out an outline.
The fact the Noir Spidey seems to have been designed with that partly in mind is really awesome, and means that this costume is going to be amazing looking in person with dim lighting.
josh, I think the shirt does need to be darker and more drab, but it's certainly brown. You're doing an awesome job on this costume, and I can't wait to see the full thing together. You're gonna look badass.
