Over the past 50 to 100 years, the color black has gone through a major transition, according to Leatrice Eiseman, color specialist and executive director of the Pantone Color Institute.
Black has gradually made its way from being a color associated with grief and morbidity to one known as a fashion staple that radiates sophistication, she said.
"It has that kind of weight attached to it ... that now brings a sense of power to the color ... beyond just funerals and grief and widows' weeds," Eiseman said.
