# Missing information for whole-screen color correction?

Unfortunately, many vendor-supplied ICC profiles do not include the information required for whole-screen color correction. These profiles can still be useful for applications that can do color compensation, but you will not see all the colors of your screen change.

In order to create a display profile, which includes both calibration and characterization data, you will need to use a special color measuring instruments called a colorimeter or a spectrometer.
