Color literally fills our world, and it plays a dominant role in how we perceive our surroundings. Scientists have been fascinated with the question of what color is ever since Isaac Newton discovered that white light contains the entire color spectrum. Our show on color explains not only how color is produced, but also looks at how scientists use color to investigate the natural world. Join CHF’s Erin McLeary and Integral Molecular‘s Joe Rucker as they whip up a batch of mauvine, the first synthetic dye, in CHF’s catering kitchen. (You can see their results in the glove pictured above.) In this week’s Chemistry in Your Cupboard, learn how you can make your own pH meter with a common vegetable. Element of the Week: Chromium.
