3. Color Management
The digital age has brought about many important gains for color-conscious professionals, whether they work in fields
such as graphic design, pre-press, video or digital photography. With these improvements, though, new challenges arose.
One of those issues confronting professionals is the variability of the reproduction of color from one monitor to another.
Every monitor has its own color characteristics. In order to effectively deal with this variability in monitor “personalities,”
it’s important to have a means of controlling, or managing, this difference. The most effective color management solution
for monitors involves using a piece of hardware (the LaCie blue eye vision) and software (the LaCie blue eye 2) to adjust
and control the color among different monitors.
To implement color management, it is essential to properly calibrate and create custom, individual profiles for all your
monitors. Once a monitor has been calibrated and a profile has been created, the profile then communicates with the
operating system and the application software to ensure that images are displayed accurately.
This section will help to explain how color is created and how the LaCie blue eye 2 utilizes calibration and profiles to help
you implement your color management solution.
3.1. Basic Issues With Monitor Color Rendering
Human perception of color is the result of the addition by our brain of the stimuli received from three types of nerve cells
located in our eyes that are sensitive to the red, green and blue areas of the color spectrum. This is why the method used
in a computer monitor to reproduce color is for each pixel to be composed of three dots that respectively emit red, green
and blue light.
