Also, there was at least one scientific graphics package from the late 1980s (I used it under BSD4.3 on microvaxen[0]) that not only had a crayon-based color picker, but used it for a simple calibration mechanism, since you could just buy a cheap box of crayons and adjust the screen colors to match. So there was at least one contemporary existence proof of "Crayola probably isn't going to go after you for this".
[0] I've forgotten the name; the main thing I remember is that your window was dimensioned in 0.0-1.0 floating point, not pixels. Some searching suggests it might have been PHIGS or GKS... and turns up a Tugboat article about FoilTeX using crayola color names similarly in 1992, so it was a more popular hack than I realized at the time.
