Crayons Under the Spectrophotometer
29th September 2011
All your Crayola questions answered.
Starting with a fresh box of twenty-four Crayola crayons I measured each with an i1 pro spectrophotometer to create a set of spectral power distributions (SPD) of the reflected light. You may not know this, but a spectrophotometer is good for much more than creating screen and printer profiles—for instance, I can tell you with some precision the color of my tongue (and my dog’s).
Well. There it is.
