Yeah...
There is a LOT of FUD online that wearing bright orange makes you invisible to deer. If that were true... just wear a fricking bright orange bunny suit and wait for the deers to start shaving with bowie knives. Although, if one of them reeks of weed and starts talking about Star Wars, RUN AWAY BECAUSE HE IS THE MOST DANGEROUS PERSON IN THE ENTIRE FRANCHISE!!!!
I can't find a good article to confirm if deer even have trouble seeing bright orange. Let's say it comes across as "grey" for argument's sake. But they CAN apparently distinguish all the shades of green and brown and that is why you are dressed like John Duty. Which means... they have a giant blob of "grey" moving around? Pretty sure that would stick out...
And for all the stories about how "the deer walked right up to me I was so hidden!": Homie. Go spend even twenty minutes walking around a park in a mountain town. Deer don't give a fuck. What startles them on your hunting trips is you talking loudly, reeking of beer and cigarettes, and constantly clanging all your metal knives against your metal pistol and your metal rifle.
Nah. Orange is good. Orange stands out. The rest is just masturbatory cosplay. Up until a couple decades ago (I would guesstimate around the time of the second US-Iraq war), hunters... just wore jeans and work shirts and, if they were "gay", orange vests. Let alone the centuries of actually hunting for survival prior to that. It is just the Call of Duty generation that insists they need to go on a shopping spree at the 5.11 store before they can go put a gooner hole in Bambi's mom.
