Consider the Environment
Our comfort level with certain colors tends to be influenced by how accustomed we are to seeing them. For many people, paler blues almost fall into the neutral category because we are accustomed to seeing blue in the sky and in the water. The cool, pale "Tiffany Box" blue that Alice chooses to employ works well in large quantity since it has a calming effect that is a nice contrast to the hustle of living in New York City.
