Two points:
One, the military after WWII did many camo tests and found that one of the best camos was "Olive drab, soiled". In my area of the USA poor hunters would get old BDUs in olive drab and spray paint "soiling" across them and use them for hunting quite effectively. So those African trackers do know a thing or two.
Two, Camo clothing is illegal in South Africa, Zambia, Zimbabwe, Uganda, and Tanzania. Not only is it non-traditional, doesn't match, and clearly shouts "we're stupid Americans, please play us", but you also run the risk of being killed. Two years ago a father and son were doing anti-poaching in Zimbabwe (Italians) and were wearing camo when they were shot dead by Parks Service. I've been on a safari before where my Park Ranger was shooting his AK-47 at poachers wearing camo right over my shoulder. Lastly, you're expressing imagery: In Africa, camo represents insurrection and military rebellion. It represents imposters claiming to be police or military to harass and assault people. It represents overthrowing current systems of government with violent force.
If I stumble upon you in camouflage in a dangerous game area I won't shoot you, but the Ranger will.
Your tombstone can read: "American. Had to do it his way. Died in the name of Mossy Oak."
