Deer may not be able to see in colour, but as with most mammals, their eyesight is understood to have have good tonal range and contrast and depth perception so it incorrect to say that camo doesn't work where they are concerned. You can do a lot to break up your outline, avoid shine (don't wear your blingy gold chains and sovereign rings and shiny sub mariners when stalking!).
Most who wear olive drab I suspect do so because their stalking environment presents lots of cover and because they don't wish to be seen in camo (???????wearing it guarantees that!). I can understand that people don't want to be dressed as some sort of paramilitary countryside terrorist...the view that some of the public might associate those in surplus clothing being somewhat undesirables which is a comment I have heard plenty enough from those ignorant of the reasons.
The less I can be seen by my quarry and by the public, the better. When stalking in local valleys, walkers have actually crossed one of the valleys before now to challenge me for shooting as they saw me carrying a rifle. I politely told them to mind their own and get back onto the public footpath. Such occasions can be avoided if we remain undetected. Binos are as much for looking out for people, as they are for stalking our quarry, something many shooters oft forget but shouldn't. The odd shot going off often scares people, understandably so if I come across members of the public, I make a point of explaining to them that they remain perfectly safe as long as they stay on the paths and don't wander off to investigate the off pop or bang. I also tell them that all shots are taken into a safe backstop so if they hear something, they needn't worry about ricochets or bullets whizzing past...it isn't going to happen. Better though imho to avoid contact if at all possible as you never know who's an anti'. Walking up to groups of people is a big no-no when armed for that very reason.
Camo has it's place and don't let anyone deride you over it. It's your choice what you wear and no-one needs to justify what they choose nor be judged by their choices.
