Apparently the reason that the current arsenal away kit is so subtle, rather than bold like the bruised banana shirt of the early 90s, that it is not allowed by UEFA rules to have kits with too much contast in the colours. The only exceptions are home kits with stripes, because they concede that these are traditional and can't be messed about with.
Away shirts have to pass tests with equipment to make sure they are either light or dark, and nothing in between. So they had to keep dialing back the pattern on the Arsenal kit until it was very feint.
Basically, with all that in mind, I can't see that the third kit will have that dazzle camo all over it, as it wouldn't pass those tests.
