I think one mistake paintball players make when selecting camouflage is picking a pattern that matches their environment instead of one that matches their cover.
If you think about how you move and go on the average field, the majority of your time is spent behind bunkers, which on most wooded fields are constructed of stacked branches or plywood. These are almost always lighter and browner than the surrounding area and it would make more sense to dress accordingly rather than try to match the field as a whole. This is why multicam and even the army ACU digital can be surprisingly effective, even in verdant areas.
Here's a picture of me, standing out in a fairly green and dark field.
Shoulda gone multicam.
