(CNN) - It's time to revert to your childhood, dust off your crayons and color away.
Sunday is National Crayon Day.
If you have kids, it's the perfect time to color with them.
You can post your crayon creations with the social media hashtag #NationalCrayonDay.
A bit of trivia: Crayola Crayons were invented way back in 1902.
The company makes three billion crayons per year, and 50 colors have been retired over the past two decades.
