Pen numbers huh? Isn't it funny how people use different words for the same thing. We never thought of them as pen numbers other than when configuring plotters. Color index numbers are what I've always known them as, indexes into the color lookup table. The dxf docs also call them color I believe. Anyway, I am not really interested in getting RGB values myself, just color index numbers. A best fit to the lookup table for the material's diffuse color would be great.Thats probably what we will do. As for AutoCAD changing their color assignments, as far back as I remember, it has been dependent on the display driver and how it is configured. For example if AutoCAD runs on the vanilla IBM VGA diplay mode that it ships with, the user can go into Config and adjust his RGB values on his 16 colors (I think) on that particular display driver. Most display drivers come with a default color lookup table and then the user can alter it to suit his needs if he wants to. So I guess it could certainly appear to have changed between versions. They probably have altered default LUTs on different display drivers over the years as well…..
