We've had berber in our last two houses and it wears like steel. The first house we sold after seven years and the carpet looked perfect. We used the same carpet in our new house. We have eight year old twins. Below is a link to what I am pretty sure is the carpet we used. You are probably going to need something a little darker than we picked to have a bit of contrast with your white flooring. There are quite a few colors to pick from. http://www.carpet-wholesale.com/item_83813/Rolls_Of_Carpet/Queen/Lucida/Pearl_Bead.php

I have gray carpet in my bedrooms. It is a flat weave from Karastan with a tone on tone stripe. I think it is the most forgiving carpet I've ever had. I do have an Irobot (recent purchase) because of the vacuuming. I have a long haired blond tabby that sheds like crazy, so I have to vacuum all the time. Of course, he sheds on the hardwood too. If I didn't have the cat, the vacuuming would just be maintenance.

All neutrals so far - you can add any colors. Depends on the look/feel/style you're going after.

I'd like to suggest that the most important thing here is more about who is using the room. If It's a child's bedroom use lovely children's curtains - there's so much around and any pattern could pick up the wall and floor colours. If a guest room and not used often I'd suggest a beautiful velvet or good quality Linen and forbid the little ones from going in to that room!!!!!! alternately a blind attached at floor level could be raised or lowered so the view is still there but with privacy from waist height perhaps. Good luck. Bee
