Howdy, Tanker 34! Welcome to the forums.
Well, you could spray the dark yellow basecoat on, then mask off a camo pattern with tape,
silly putty, or any masking medium of your choice, and spray on your camo colors. It might be difficult to get soft edges with masking, but you certainly could create a hard-edged camo no problem.
I've never tried it myself, but I understand a good soft-edged effect can be achieved by applying a slightly raised mask (raised with rolled tape or
silly putty) and spraying with the can at 90% angles to the masks.
It's worth a try!
