And we all see how well the UN functions as a military unit.........
The UN does it for a very specific reason. It's done to identify them AS the UN, not as a tactical camo. They are not trying to be inconspicuous, they are TRYING to stand out and be noticed. Not a valid example. Air and naval units are a completely different aspect. They use white because they deal with air, water, and cloud camo. It's the same reason you don't see soliders wearing woodland camos when deployed in the desert.
I don't think you can honestly say with the way mechs fight that contemporary camouflage would ever be effective. Modern camo is used for units that are trying to stay hidden. Snipers that don't move. Even camo'd snipers stay still because movement will give them away. Tankers that fight from just barely visible ranges, and low to the ground. Mechs are TALL machines that stride into battle, often sticking out above the horizon (not unlike battleships), and fight at very close ranges. Camo on mechs isn't meant to hide the machines, if anything it's to obfuscate distinctive parts so its harder to tell if you're aiming at an arm, torsos, or leg*. Your mech isn't going to be hidden a from a few hundred meters away just because your paintjob matches the grass under your feet or the rock cliffs behind you (especially if you're not standing still), but you can have a paint pattern that makes it harder to tell which parts are which, or where some parts begin and others end.
And also like the UN, Mech pilots would WANT to their targets to know who it is that's coming for them. Might as well have a hotshot paintjob since that forest camo is absolutely useless at any range you'd be fighting at anyway.
*Battleship "camo" was also not meant to "hide" the ship, as doing so is a silly thing when it sticks out above the horizon. Instead, ship camo would often try to make the waterline look higher so that the ship looked farther away or they would paint patterns that made it look like it was facing at an angle different than its real angle, which would make the enemy misjudge where to fire their cannons..
