The world we live in is a colorful place (except in our dreams, which are mostly black and white, which is odd when you stop to think about it). Though we are surrounded by color and new colors are invented all the time, some colors have completely disappeared from our lives, or are very rare, or are becoming extinct. This list is a sampling of some of those pigments or colors once found in nature, in consumer products, manufactured goods, building construction, etc.
