Zinje,
Displays that accurately display color maintain the level of red, green and blue primaries as compared to their levels in white (gray) and their complements. When a display deviates from these standards it will alter the color balance. You can for example have blue setup correctly (color/hue), but the level of red versus its level in white may be too high. This is called red push and is found in many consumer sets.
The effect is to shift things like skin tones to the red side avoiding an undesirable shift to green. The best way to check for this is to display the SMPTE color bars and adjust the color and hue to correctly set the level of blue. A set that shows too much red in objects after that adjustment is "pushing" red. You can also "push" green or have problems with the level/hue of the green and/or red compliments (yellow, magenta, cyan).
Color accuracy can also be effected by the display's primaries not matching the SMPTE standard color coordinates. The color of gray on a display can also shift the colors. It must be set to match D65 (a standard color) at all levels otherwise the level settings for the primaries versus white (gray) will be off.
When gray shifts to blue at low levels, for example, all things on the display at that level will shift toward blue.
