Color us sad: Crayola is retiring the dandelion crayon. by Aaron Smith @AaronSmithCNN March 31, 2017: 11:04 AM ET. The hottest news of the week broke a day early: Crayola is retiring the yellowish dandelion crayon from its rainbow of colors.
First invented in 1903, the original Crayola box contained only eight colors, including red, orange, yellow, green, blue, violet, brown, and black. It sold for only a nickel. A chart posted on Reddit shows how Crayola crayon colors have grown from eight basic hues to dozens in a little over 100 years. Now, there are 120 colors in the Crayola color wheel. The names have evolved as well to include colors like âdenim,â âscreaminâ green,â âdandelion,â and ârazzle dazzle rose.â Stephen Von Worley, a visualization researcher at Data Pointed, created the visual crayon chronology with his pseudonymous friend who he calls Velociraptor.
