You gonna' have to post a pic to get anyone's opinion!
From the sound of it, though, you probably don't have any problems. First, I'm sure the paint could fade more than we'd ever do it. Second, If you think it's too light, once you get to that point, you can put a raw umber oil wash over it and it will darken it right up. Need to be careful, though, it's easy to darken it too much.
