The Blackness of Black

In what remains one of the central accomplishments of cognitive anthropology, Berlin and Kay (1969) demonstrated that the diversity of human color systems was built on a universal infrastructure, with black and white being the most basic colors in all systems. The analytical focus of their work is a structural system divorced from the messy tasks of actually using color terms to make relevant d...

Structurally assisted blackness in butterfly scales.

Surfaces of low reflectance are ubiquitous in animate systems. They form essential components of the visual appearance of most living species and can explicitly influence other biological functions such as thermoregulation. The blackness associated with all opaque surfaces of low reflectivity has until now been attributed to strongly absorbing pigmentation alone. Our present study challenges th...
