Colourful variety not only in a bazaar: many industries rely on inorganic or organic pigments to lend colour and brilliance to their products. Pigments are increasingly taking over other functions, too, such as UV and rust protection. Find out more in our special topic that informs you about new market developments, innovative products and leading providers.

Egyptian blue is one of the oldest manmade colour pigments. It adorns, for instance, the crown of the world famous bust of Nefertiti. But the pigment can do even more. An international research team led by Dr Sebastian Kruss from the Institute of Physical Chemistry at the University of Göttingen has more
Throughout history, people have sought vibrant blue pigments. The Egyptians and Babylonians used lapis lazuli 6,000 years ago. In 1802, a French chemist synthesized cobalt blue. More recently, in 2009 scientists discovered YInMn Blue, otherwise known as "Oregon Blue." But most of these pigments have more
A new molecular gel recipe developed at the University of Michigan by Anne McNeil, Arthur F Thurnau Professor of Macromolecular Science, and is at the core of a prototype for a more accurate lead paint test.The new test is more clear and accurate than its counterparts. It consists of a vial that ... more
Although the ancient Egyptians already used inks 5000 years ago, inks and their properties have been continuously improved and refined over thousands of years. more
The latest in the Colourful Chemistry series looks at the inorganic compounds that give many paints their colours. This shows a limited selection of the most common compounds, and there are many others; there are also a large range of organic based pigments, which aren’t discussed here. Generally, p more
Lipstick is one of the most commonly used cosmetic products – and a range of chemicals are required for its production. The choice of these ingredients is carefully considered to provide the desired colour, glossiness, and indelibility. A single stick of lipstick will contain several hundred differe more
With blackberry season approaching, here’s a quick graphic looking at blackberry colour chemistry. Posts have been a bit few and far between over the last week or so as I was off at ACS Philadelphia (post on that to come shortly), but the pace will be picking back up again this week! more
Photosystems I and II convert solar energy into the chemical energy that powers life. Chlorophyll a photochemistry, using red light (680 to 700 nm), is near universal and is considered to define the energy "red limit" of oxygenic photosynthesis. We present biophysical studies on the photosystems fr more

Pigments have been used by people as colouring substances for centuries. Although naturally occurring compounds and elements were originally used for making pigments, e.g. iron oxide, manganese oxide, ultramarine and carbon black (soot), with the development of industrial chemistry from the 18th century onwards, there was an ever-increasing range of synthetic pigments available. more
