The Blue Economy - Innovation No.8: Color without Pigments

2012-04-05 1

Have you ever wondered why the humming bird and the peacock shine with bright colors? They simply do not have color, but rather use optics to block certain colors and show others.

Oxford University professor Andrew Parker studied light, eyes and colors throughout history. At the Natural History Museum of London, he oversees a collection of more than 1 million bugs, many showing off the brightest colors. Yet, none have any pigments. Parker understands how insects and birds create color and reproduces these effects in glass, textiles and cosmetics.

Color has been associated with chemistry, often requiring heavy metals. Parker does away with this, creates color without any color pigments and offers a competitive alternative to color pigments. Since just about every artefact in society depends on shades of color, there is no industry that remains unaffected by this innovation.
