Celebrated on March 31st
Crayon manufacturers, Edwin Binney and C. Harold Smith, sold the first eight packs of Crayola crayons for five pretty pennies. It included the same colors available in the eight-count box today: red, blue, yellow, green, violet, orange, black and brown. There are 120 shades available now, to be exact. Officially, there are about a dozen more, but they are impossible to get your hands on because they're retired or special edition (like Oprah's crayon color "The Color Purple").
During crayola's 100th anniversary in 2003, founders Binney & Smith asked children to send in any unwanted blue "leftolas." (the term used to describe leftover Crayola crayons.) They wanted to created a giant blue crayon and with the help of 123,000 crayons sent in, they were able to create Big Blue, a 1,500 pound crayon that is 15 feet long and has a 16-inch diameter. Crayola fans can go see Big Blue at the Crayola Experience tour in Easton, Pennsylvania — blue was chosen because it's Crayola's most popular color.
There have been over 300 official crayon manufacturing companies, although only a small amount exist now.
