I am thinking of doing my rebuild in Resene Half Tea in the lounge, bedrooms, hallway and stairway, and Resene Quarter Tea around door frames, doors, window sills and in the kitchen and bathroom. I'm having a grey carpet. Will Resene Half Tea and Resene Quarter Tea go with grey?

I don't see why a grey carpet and your lighter Resene Tea colours wouldn't work together but it does depend upon which particular grey you were considering. There are so many to choose from and some may be better than others. If you get several samples and take them to your home to view in daylight and night light and right up against the paintwork you may find a grey colour that suits. It is all about what looks good to your eye.
