Debbie [Millman] asks: Why do you think so many people wear black in New York City?
Massimo replies: Because of the image.
Debbie Millman: How would you describe it?
Massimo Vignelli: To begin with, black has class. It’s the best color. This is no other color that is better than black. There are many other colors that are appropriate and happy but those colors belong on flowers. Black is a color that is man-made. It is really a projection of the brain. It is a mind color. It is intangible. It is practical. It works 24 hours a day. In the morning or the afternoon, you can dress in tweed, but in the evening, you look like a professor who has escaped from a college. Everything else has connotations that are different, but black is good for everything. My house is covered in black.
Debbie Millman: Are all your clothes black? Do you wear all black?
Massimo Vignelli: Yes. Always. Always.
