...that turns out to be just what you want in a fruit or vegetable. As a rule of thumb, says Althea Zanecosky, a spokeswoman for the American Dietetic Association, the more colorful the produce the better it is for you. "A fruit or vegetable with a lot of pigment is actually very rich in antioxidants," says Zanecosky, pointing to the deep greens, dark yellows and vibrant oranges that fill the fruit and vegetable section of supermarkets each autumn...
...course, in addition to its revelatory value as the residual evidence of a ‘genius’ at work, this exhibit includes works of astounding visual and artistic expression—captivating, as well, for the mere, yet sublime, settling of pigment on the paper’s surface. The images range from obscure compositions to variations of the quintessential de Kooning women...
...Ackroyd and Harvey turned to purely scientific enquiry to overcome a flaw in the material. Like photographic paper, an image printed on grass will fade if it is not fixed in some way. The images Ackroyd and Harvey created would last only as long as the chlorophyll (the green pigment) lived. Once the grass died, so did the chlorophyll and the image would fade in a relatively short period of time, several months at most. So Ackroyd and Harvey teamed up with scientists to overcome the fading problem. Working at the institute of Grassland and Environmental Research, they found...
...risky way to win admiration. Hydroquinone is available only by prescription in Europe and closely regulated in the U.S. In small concentrations, the bleaching agent poses few problems and is often used by dermatologists to treat various skin conditions. But prolonged use stops the production of melanin, a natural pigment that protects the skin from the sun, and increases the likelihood of skin cancers. Damaged skin cells also "make the skin very weak," says chemist Wangai. Veins show through and, over time, the skin may actually become darker and develop hard nodules. "But even when they know that, women keep...

Then he turned to painting people, or rather embalming them in his characteristic thick, smooth and (when used to make flesh) slightly rubbery pigment. After moving to San Francisco in the early '70s, he took his eye outside and did cityscapes--those strange, plunging perspectives of the hills and highways of the city, translated into gravity-defying slices, with cars clinging to the asphalt like flies to a wall, as in Apartment Hill...
