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

[Compagnon Raphaël]

Hi

This RAL and xKxxx paints colors list is probably the same as the list appearing in the annex of my Radiance tutorial http://home.hefr.ch/compag/ref/RADIANCE_tutorial_E.pdf
where their reflected Yxy values (measured under the standard illuminant D65) are given.

These values were measured in years ~1991-1993 with a colorimeter at LESO-PB EPFL Lausanne (where I was working at that time) on paper paints samples. The xKxxx or xExxx color names are coming from a Swiss standard notation defined by the paints manufacturers association VSLF http://www.vslf.ch/
This tiny database was built for the ADELINE package http://www.ibp.fhg.de/wt/adeline/index.html

I have here a list of 50+ RAL and xKxxx (like 2K216) colors.
I don't remember where I got those from and if I'm allowed
to share them in public. I also do not know if the Radiance
RGB values are validated or 'just' calculated.
