I would find a safer place to live.Blue, red, green and I think black around here. But with the black it is specific items worn in a specific way. (The gang is known as "The Family") The Mr. and I are safe enough wearing black jeans and t-shirts. I'm not sure if yellow is also to be avoided or not, it might be now.
Keep in mind, I live in a tiny, podunk town a good chunk of the residents live at, or below poverty level. In this town, you don't want to wear either red or blue, ESPECIALLY if you go down on the East side of town. (The slum.) Our friend and his girlfriend (now wife) got mugged at gunpoint in broad daylight in that neighborhood, and he lived/grew up there! He was one of the few white boys who could semi-safely walk through that area. Still, he got chased out of the tenament by thugs (gang members) armed with HEAVY WEAPONS some years back. I am not kidding, and he is not the sort to lie about that. This town is on a major drug route.(There are also a *LOT* of meth cookers and meth addicts here.) I'm not kidding when I say if the Mr. and I go out walking at night we wear chains, and carry knives. Any sane person would. More than once we've been followed by a fellow, just casually walking behind us you know. Until he saw the chains, then he went off elsewhere to find someone easier to mug.
