Colorímetre

Here’s the next best thing to a panel of color experts when it comes to judging - or matching - colors. It’s a colorimeter - an easy-to-build electronic gadget that literally measures the color characteristics of any object or surface. You’ll use it to match the color of paint to a previously painted surface; to gauge the effects of color change caused by painting two dissimilar surfaces with one color paint; and, to study the fascinating science of color.
