Pollution doesn't have a thing to do with oil color, it is the heat of the engine combined with a tiny amount of metal from the moving parts of the engine.
The added detergents wear down after 3k miles or so, unless you get the high milage dino oil or synthetic oils that can last 10k miles before breaking down.
Used oil is just black black, it should not be a brown chunky/sludgy mess and if it is then It is has far too many miles on it.

If it needs changing it is usually very black and the thicker the more you need to change it.
Believe it or not oil starts on looking like vegetable oil... Shows what pollution does to it.
