Diabolic I've looked into it and there's some requirements to have "full black" guns. "Two tone" anyone can use (at least 50% of the gun must be in a non gun colour including but not limited to: UN Blue, Hot Pink, Safety Yellow, Blaze Orange, Neon Green, Red etc. (ie. can't use brown, tan, green, or "chrome"/silver/stainless steel))). Not too sure about clear though but I assume it satisfies a non gun colour since clear isn't really used by any gun manufacturer.
Also you have to register with either the UKARA or have a "site membership" elsewhere (ie. a local *legitimate* field with insurance coverage who can vet for you playing at least 3 times every 2 months (not sure about the "down season" though when it's too cold to play)). Supposedly with the VCRA though the airsoft community is supposed to be "self-regulating" and that's where the UKARA and site/field memberships fall in.
