There are quite a few steps involved in getting the image to a printer. Lens itself may have a colour cast. Different lenses have different colours and transmission properties. That is why in cinema, a colour & transmission balanced set of lenses are so popular and demand high price. Here each lense in the set will have the same colour and transmit same amount of light at a given f stop.. Sensor colour response. That varies from design to design and from sensor to sensor. For most consumer products, a basic colour calibration is carried out and embedded in the camera data base. Still each camera manufacturer sees it differently, that is why there is Nikon colour, a Canon colour and Sony colour and all of them differ subtly.. RAW processor, has to generate RGB from the Bayer pattern and assign it to each pixel. Depending on the algorithms, different RAW processors result in subtly different colours.. Then there are monitors and printers. Each has innumerable varieties of setting affecting colour.So in general, it is futile to expect perfect colour matching between the object and the image displayed on the screen, as there are simply too many parameters to fiddle with. As long as the colours are nearly there and can be tuned in PP, it is fine.</blockquote>
