Many designers and photographers have problems associated with color reproduction.
Because of different mechanisms which are based displays (RGB, red-green-blue) and color printers (CMY, cyan-magenta-yellow), there is a difference between what is seen on screen and what is printed. Therefore, the whole story about pre-press inserted color profiles and other elements that make life easier for those engaged in such activities. However, it would in due course could be changed.
In fact, Apple has come to a seemingly simple idea – throw CMY monitor. In this way, users with special needs could receive a display that would eliminate the problems in the color palette. For now, no concrete plans, but Apple has filed for patents in technology that would result just mentioned.
Seemingly, there are problems with the color reproduction, given that CMY palette covers a narrower part of the visible spectrum, but Ars Technica reports that the question of how much it will be evident in practice, since most RGB monitors, though nominally supporting 16.7 billion color, in practice, very far below that figure.
In any case, it is expected that these monitors targeted professionals, and it is expected that normal users still hold the RGB display.
