You make a very good point there KG2V.

Camouflage is all about blending with the background and maintaining patterns and colors that don't catch the eye. Medium to charcoal gray, dull browns, subdued and muddy greens like OD green, are all earth tones that the eye tends to slide over without notice. Grays and subdued blues don't match the color of much in particular but they work well with the visual haze that is seen in the distance and generally a medium hue that don't stand out against many backgrounds. Black, on the other hand, stands out against everything and remains noticeable until lighting is so low that virtually any color would be invisible.

But your notice of contextual camouflage is quite apt. Blue collar workers have long favored Dickies, and similar brands, because they are inexpensive, tough cotton poly blends that wash and wear well, and hold up to hard use. Visually these are even better for urban camouflage because much of the Dickies line come in subdued hues.

The rural equivalent of Dickies, with a considerable amount of overlap on both sides, is Carhart, and similar brands. These tend to come in earth tones and are respected for their durability.

High-top work boots are a good choice both because they blend but also because they are tough and adaptable. These fit into any urban or rural environment.

Mix and match Dickies and Carhart and you pretty well blend anywhere. But as the ladies know, to make an outfit 'pop', or in this case disappear, you need to accessorize. A feed cap blends in rural areas. A baseball cap in urban.

A hardhat, traffic vest (generic ID clipped onto the front) and clipboard will get you ignored so profoundly that it is virtually a universal pass.

I'm tempted to try my luck with a saffron wrap, a fistful of pamphlets, and some good old fashion pseudo-religious gibberish. I suspect that you can slide on by a lot of situations wearing that outfit.

Load all your stuff into a grocery cart, pile assorted trash on top. Strip down to boxer shorts with a parka on top for outfit. Get a cheap poly blanket in a garish color, roll it in the mud ,[censored] and spill beer on it so you smell right. Drape this over your shoulders. Talk loudly to yourself about mind control to complete the picture. In that outfit you have a free passage through a lot of tight spots.

The point here is that color matters if you wish to blend into the physical environment. But the style of clothing can help you blend into the pattern of humanity and motion. What your going for is to either blend into the pattern of local life and to escape notice. Or to stand out in a way that gets you pegged and discounted as harmless and not worth messing with. The key is to take advantage of existing types, stories and prejudices.
