Spectrophotometer Analysis of Crayons
Volhav writes "Like many as a child, the photographer Mark Meyer wondered what the difference between Yellow-Green and Green-Yellow was in that Crayola box of crayons. Using a monitor calibration tool and the Argyll 3rd party software he evaluated a box of 24 Crayola crayons, and plotted them out with sRGB values. He even included a nice printable poster size version of the chart in his blog post. For the geek or curious this was a pretty interesting plot."
Note that chemists have real recording spectrophotometers, not just monitor calibration gadgets. I spent way too long in my youth, if I recall correctly, classifying iron ore samples using one. Its a fairly elegant technique because accurate ultra wide range light sensors have been old stuff for decades. It seems like I took an entire 200 level quantitative chemical analysis chemistry class where all we did was F around with a spectrophotometer in different ways.
If I recall correctly, the infrared ones were the cats meow before NMR got "cheap" for classifying organic compounds.

Has anyone done a similar plot evaluating the taste of the crayons?
And who pinned these mittens to my jacket?
