“Color clearly has aesthetic value, but it can also carry specific meaning and information,” says Andrew J. Elliot, Ph.D., professor of psychology at the University of Rochester, in New York. He and a team of researchers concluded that, “Seeing red is not good before [tak- ing] a test measuring performance” (Jour- nal of Experimental Psychology: General).

developed, non-invasive cancer treat- ment, involves injections of a light-sen- sitive solution, followed by shining laser- emitted blue light on internal tumors or light-emitting diodes (LED) on surface tumors. A National Cancer Institute fact sheet explains how such light kills can- cer cells and shrinks tumors.

Pantone, a leading provider of color systems to businesses worldwide, annually recommends a specific color that it feels best connects with the current zeitgeist, or prevailing spirit and mood, so that manufacturers of paints, kitchenware and fabric will produce the look people will want to have around them. In 2011 Pantone picked a vibrant pink.
