Titan will mark anything that is new in our house. So when we have guests, we make sure they put there shoes where the dog can't clam them. When dogs mark, it's with pee. Not sure about the color. Maybe he had more water to drink that day and it was lighter than usual. Next time smell it. If it smells like pee it's pee. and pee smells when it's wet and (I think) more when it's dry. My boy doesn't hump anything, except Roxi when she's in heat and that's only when she's not humping him. If you get him a humping toy take pic's I'd like to see that, ha ,ha.
The best way to cure him of these naughty habits are to get him fixed as soon as he's old enough.
