Hi,

if it is Autocad color index, there is an example here

ACI Color to RGB

Hello @Drbohlav you can try to use the LookUpAci() and/or LookUpRgb() methods (ObjectARX ) to convert ACI to RGB here an example color_index = Autodesk.AutoCAD.Colors.EntityColor.LookUpAci(255, 255, 0) RGBint = Autodesk.AutoCAD.Colors.EntityColor.LookUpRgb(color_index ) Blue = RGBint & 255 Green = (RGBint >> 8) & 255 Red = (RGBint >> 16) & 255 rgb = [Red, Green, Blue] OUT = color_index, rgb [image]

color_index = Autodesk.AutoCAD.Colors.EntityColor.LookUpAci(255, 255, 0)
