We were trying to replace an existing cellular blind that had broken.  Of course, white by 1 mfg is not the same as white by another.  We tried to get a replacement from the same mfg but they were out of stock, so I tried Wayfair.  The white blind we recieved is great, just not the same white as what we already had.  We are keeping it because it is only in the bedroom and it looks fine.
