What is needed is a method to put them all back where they belong. To do this, we use a series of standard color charts and calibration images. Before we go off and start making random adjustments, it is absolutely necessary to first get our own environment calibrated. To do this, we must employ some more techie stuff. First, it is essential that we adjust our color temperature variable.
Various monitors come with different phosphors in the picture tube which are used to display color.
There are different tube manufacturers which incorporate different phosphor techniques and composition. There are others however most computer screens are either Hitachi or Trinitron varieties. Some monitors such as Samsung and Sony allow you to change the color temperature of your screen. These numbers represent a temperature on the Kelvin scale where absolute zero is the point where motion of molecules stops and has no energy at all. Think of these as the surface temperature of the Sun or the filament of a turned on light bulb.
