Hi list I wrote a script that captures Lab coordinates from spotread (in reflective mode) and places point in vrml file. For visual comparison purposes, my vrml file contains reference gamut body, because I thought that it shows surface colors limits. But today, "bright" orange marking pen on paper gave me a point that located noticeably far away from reference gamut boundary. So, as I learned, reference gamut is not equal to MacAdam (theoretical) color limits. Where I can find optimal colors solid in form of .gam, .wrl or .icm file? Thanks Sorry for my English
