We have one room - my studioffice that gets full southern sun all day. All floors and carpet fade when getting that much sun. The flooring in front of the sliding glass doors in the room has faded slightly. In the photo below, I marked where I rolled up an area rug in the room so you could see how the flooring has faded. The full bath with the flooring is in a bright and sunny room, but since the sun isn't on it all day long, it has not faded.
