Calibrating your display
You can easily adjust your display to show accurate color using the Display Calibrator Assistant. The colors you perceive on your display can be altered by many factors, such as ambient light, the position and angle of the display, and the age of the display. You should calibrate your display regularly to ensure accurate color.
To calibrate your display:
Open System Preferences, click Displays, and then click Color.
Click Calibrate.
The Display Calibrator Assistant walks you through calibrating your display and then creates a calibrated color profile for your display.
If you wish to do a more detailed calibration of your display, select the Expert Mode checkbox.
