Well as a kid I used to always get told to buy some colour in my normal clothes as I only tended to wear black. So I got out and bought some dark blue/black jeans!!
I now wear mostly dark or subdued colours in town and country. My only concession to colour are my outdoors kit that have bright red detailing as that was the trend over the last few years in hill clobber. Got black windshirt with red zips, black hard shell with red zips and red cuff closures, etc., etc. My fleeces are mostly blue, grey or black. My trousers are black, brown or rohan's green/khaki (don't wear these anymore as I don't like them). My rucksacks are blue/grey, black (custom job from Aiguille so I chose the colour of the fabric), black, blue or blue/yellow all bought for the spec not the colours. My tarp is green (nice darkish green), Tents are all dark green with black details, bivvy bags are either blue (Rab SZ) or red (Rab Storm bought for £35 so beggars can't be choosers with the colour at that cheap price).
Anyway apart from the tarp and one of the tents that I use in the hills (as opposed to car camping) none of my gear or clothing used in the outside has been bought for colour more for specifications and lastly for colour. I don't think I need to be discrete in appearance in the hills. Even wildcamping in England or Wales I have no problem with being obvious or discrete. I don't see a problem but that is probably due to me only wildcamping in areas where it is legal or the landowners have a history of accepting it such as in Scotland or the Lakes. I guess if I camped in the Forest of Bowland I'd need to be more discrete in my colour choice. Fortunately the gear I have bought happened to be such colours as green and subdued colours.
As far surplus gear in cammo being cheap I would have thought that a lot of cheap surplus gear is in plain green (olive green), black or cammo. The same make too. IIRC Vulcan bergen for example is available in cammo, olive green and even black. In that case if I wanted such a sack I'd never get cammo. Its down to the pre-conceptions people have about people wearing or using anything in cammo colouring. That is glamourflage excepted of course. You do see people in cities wearing a sort of cammo clothing as a fashion statement and indeed cammo has been in and out of fashion among those sorts many times. None of it is DPM type cammo though
