No no no, none of the above, only play insured recognised sites, sure two tones suck, but criminal records suck more.
If you don't want to stand out at a site, mask the bright parts of your gun with a suitable camo tape, therefore you won't have broken any laws, & once your 18, you can spray it legally.
Edit. Rocketdogbert pipped me by 5 seconds, obviously I'm not say disregard his post, just no playing in public places etc
