I had the opportunity to speak with a reasercher who specialized in mosquito borne illness and he confirmed that mosquitoes are also attracted to drastic color variations. I asked him this becasuse on one of my camping trips (which I nicknamed skeeter island) I noticed they literally swarmed around anything we had that was black or very dark colored, almost like it was bait. Apparently colors that don't contrast too drastically with the environment are better for keeping the skeeters away.
