Expect to see a lot of single crayons appearing on eBay: For the first time in its history, Crayola says it will retire one of the crayons in its classic 24-count box, meaning the color will no longer be used in any Crayola products, reports PIX11. Will it be carnation pink? Cerulean? Or boring white? Crayola is keeping mum until National Crayon Day on Friday, when it will reveal its decision live on Facebook. It's even counting down to the event on its website. In the meantime, as if to calm the inner child in all of us, a rep tells Mashable that the retiring crayon will be replaced with "a new, exciting color." (More color stories.)
