Crayola's new 24-pack won't include the color Dandelion, the crayon-making company announced Thursday. The golden-yellow crayon, an iconic color in Crayola's classic pack, was introduced to the box in 1990. Crayola is giving it a day before it announces which crayon color will step up as Dandelion's replacement. The big reveal will happen on Friday — which happens to be National Crayon Day — at an event in New York City's Time Square that will be livestreamed on Facebook. Devastating as Dandelion's departure may be, CNBC reported this isn't the first time a crayon has left the box.
