About the color Alien Armpit

A crayon with a smell

Alien Armpit is the name of a scented crayon from Crayola. The Wikipedia list of Crayola colors puts it in the Silly Scents box of 16 crayons. There it is the scent given to the Yellow Green crayon.

Why the code is only a guess

Crayola does not publish screen codes for its crayons. #84DE02 comes from a widely copied list on W3Schools, which calls its Crayola codes rough guesses. That list also puts Alien Armpit in a Scary Scents box instead. Wikipedia gives the crayon's color as the paler #C5E17A. So take #84DE02 as a bright yellow green, not as the exact crayon. Close colors on this site are inchworm and yellow green.
