If you've got a sample of the color, sure--you do colorimetry and  
convert the values from the colorimeter's color space to the Radiance  
color space. It takes some care to choose the sample, however.

We wish! Developing one, or tools to generate them from other data is  
a project that so far has not been addressed.
