[Radiance-general] Color reflectance values and materials..

[Mark Stock]

Jack,

Forgive my ignorance on the topic, but how do you convert those 
values to something that looks right in Radiance? I've tried just 
using RGB values like the ones from the site, but everything is 
simply too bright. And scaling them down uniformly seems to 
change the hue.
