Colour change in one room where carpet was joined. Cavalier Bremworth rep assured me that it was because I am a one person household and would improve when it had been walked on and the fact that room had a lot of light in meant that it looked different. I accept that the carpet was all off the same roll but it is disappointing that the change remains obvious to me. One room in particular has the problem but my living room also looks different from a join which runs right across the room 1050mm from the ranch slider which is my main entrance.
