I love gray/grey. I use it a lot. There are cold grays, for sure, but there are some that read as warm. A gray is far less harsh than black (which I also love and use a lot), and less likely to get dirty and dingy looking than white or cream. Plus a lot of home decor is geared toward grays now, so quilts with gray sell well, go for high prices at charity auctions, and tend to make recipients who are setting up new homes or nurseries very happy.
