in my not opinion, I would personally leave it two toned and not bother from my experience as an adult people won't judge you or think any less and tend to be more welcoming, i have lost track of how many guns i have seen ruined by tape and paint that locked the gun up or look worse than the two toned originally.
i work at a woodland site and to be fair their is such little tree coverage anyways i wouldn't worry so much about "camo" i would focus more on enjoying it and having fun. save the money on tape and paint for bbs and pyros for the day.
but that is just my view
