He then thanks the many physicians, researchers, family members, and friends who came together to memorialize his son and create knowledge, hope, ...

CIE Whiteness and Tint: Possible Improvements

To introduce some measure of standardization in the face of the endless variety of whiteness formulas being used, the "Commission internationale de l'éclairage" proposed in 1986 a whiteness and a tint formula for practical trials. The formulas in question were simplified derivatives of those used in the Ganz/Griesser method. The difference is that the CIE proposes fixed formula parameters and r...

The colored appearances of animals are controlled by pigmentation, highly periodic ultrastructure, or a combination of both. Whiteness, however, is less common and is generated by neither of these, because it requires scattering processes appropriate for all visible wavelengths. We report whiteness resulting from a three-dimensional photonic solid in the scales of Cyphochilus spp. beetles. Thei...
