Dude, stop trolling please. If you actually lived in this kind of neighborhood, you would know the EXACT boundaries of EXACTLY where you could get away with wearing EXACTLY what kind of colors on EXACTLY what parts of yr body, and EXACTLY what would thereby be signified.
You are doing a disservice to anyone reading this who might actually want to understand this sort of situation.
I grew up in the Rollin 20's Crip territory of Long Beach in the '80's and '90's. Back then, I could draw you fucking *maps* of exactly which sets controlled which blocks ("bloccs"), and which areas were hot/contested, and which areas were under siege from the Cambodians when they started immigrating into the neighborhood en masse, and... yeah.
If you lived in that kind of neighborhood, you'd be able to draw maps, too. Because yr safety would depend on it.
Also-- Not all Crip sets wear blue. The Rollin 20's Crips actually wore black and gold. Don't know if they still do. There were also Crip sets who wore purple (Grape Street), and other colors, too.
My point being, if you ACTUALLY lived in an ACTUAL gang neighborhood, there might be a whole shitload of other colors that'd be off-limits to you, too. Not just red and blue, friend.
You can go back to watching Straight Outta Compton now.
