“The perceived color changes in relationship with the angles of observation and illumination. This effect can only be produced by nanostructures that influence how light is reflected,” says UA post-doctoral researcher Brani Igic. He used experimental manipulations in conjunction with angle-resolved spectrophotometry, scanning electron and atomic-force microscopy, optical calculations and chemical analyses to examine the mechanical construction behind the eggshell gloss and coloration.
