White polly kitchen looks grey in my new kitchen

I have just finished a kitchen renovation from HN. I removed part of a non bearing wall to open up the area. The cupboards I choose were Linea White Poly. With a nogat cesar stone bench top, and Red decoglaze splash back. The kitchen is exposed to lots of light. UNFORTUNATELY the kitchen looks a dirty grey even with the lights on. This is very disapointing as it does not do the kitchen justice. Has anyone else had this problem. Cassie

Are you saying that the sample you have looks fine in your kitchen, but the actual cabinets look different? If there is a discrepency between the sample and the finished product you may have a case to have it rectified. However if the sample and the cabinets are the same, but simply don't look great in the natural light of your own home, I'm not sure what you can do about it.
