Generally, if I am hiking I wear Earth tone colors, which I normally wear anyway. Hunting is blaze in safety situations or a mix if camo and Earth tones in others. I have heard both that insects are attracted to dark colors and also that they are attracted to bright colors. I wore a bright blue shirt today at a park and had plenty of mosquitos and deer flies circling and attacking. Not sure if normal Earth tones would have helped though as they come after me then too. Older school woods wear was red flannel/wood and such work well to keep some one from taking a shot at you thinking you are a deer, but turkeys have red heads...So, also, in bear country wouldyou wear camo to hide from them or bright colors to let them know you are there and to steer clear? Thoughts? Thanks!
