Painting your kit with camouflage patterns is one of those weird things that's not quite for beginners but is incredibly easy and satisfying to do. Getting camo to come out just right needs only a bit of extra materials and some patience,
Before you begin to contemplate camo designs, you should at least be comfortable painting your kits with an airbrush. While it's possible to hand paint or use spray cans, there are some issues that arise. Spray cans typically leave a thicker coat of paint than airbrushes. Normally this isn't a problem over entire parts where, after assembly, you can't tell where the paint begins and ends. Camo typically involves masking hard edges of overlapping colours and these edges can become unsightly with thick paint coats. While I've never tried hand painting when camo has been masked out, I would be concerned with the potential for moisture to seep into the edges.
