PdfGenerateConfig.ColorOptions Property
Print color-management options - ICC output intent, black generation, and real ICC device-to-device color conversion (ConversionMode - see ColorOptions’s remarks). null (the default) behaves as OutputIntentProfile being unset - fine unless PdfXConformance requires one, in which case generation throws.
