Are color viewing booths built to some national or international standard?
Yes. Color evaluation booths, used for imaging applications, should conform to ISO 3664:2000. This standard specifies the surround color of the booth, the light sources to be used, with their minimum color characteristics required, the light levels that are required on the viewing surface, and procedures. The daylight source is D5000, as specified by this standard, and is used for both reflective and transmissive art work.
