NCL ages and "yellows" over time. Direct sunlight is not good for the lacquer or the wood. Probably has less affect on Taylor's finish, as it is a poly based finish. I've protected my blond Guild from direct sunlight for 19 years and yet it's developed that beautiful aged glow about it. It just takes time. If you try to rush it, you may do some damage. Be patient.....
Great color, eh?
