(Bonus points if you can match the colors used in the 1970 BART expansion plan map.)
Interesting how some colors were discontinued — green-blue, blue-grey. Those seem fundamental — Crayola insults color history! (Kidding.)
WS’s friend Velo seems to have discovered a color power law:
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!
