Assume we get data on dogs pigmentation on this rgb scale. Then a dog with a pigmentation of rgb(0,0,1) would fail the 'is the dog black' test. An a dog with a pigmentation of rgb(255,255,254) would fail the 'is the dog white' test.
The only way for Jon's algo to work would be for a user to provide their definitions of black and white on the rgb scale
The color card sorting example is not relevant either as the color of the cards will always either be rgb(255,0,0) or rgb(0,0,0).
