"To create the chart, Velo gently scraped Wikipedia’s list of Crayola colors, corrected a few hues, and added the standard 16-count School Crayon box available in 1935.
Except for the dayglow-ski-jacket-inspired burst of neon magentas at the end of the ’80s, the official color set has remained remarkably faithful to its roots!
Ever industrious, Velo also calculated the average growth rate: 2.56% annually. For maximum understandability, he reformulated it as “Crayola’s Law,” which states:
The number of colors doubles every 28 years!
If the Law holds true, Crayola’s gonna need a bigger box, because by the year 2050, there’ll be 330 different crayons!"
