What is color?
There are two types of cells in the retina of our eye that are responsible for our perception of color: rod and cone. Cones, which are sensitive to color, function best in bright light. They exist in three forms, each differing in the wavelength of light absorbed ( LMS ). Rods, on the other hand, are sensitive to the intensity of light. In the human eye, rod cells allow us to distinguish and detect objects in the dark; however, since their sensitivity to light is better than cone cells, our ability to perceive the color of objects in an area of low light becomes poor.
Let’s take a look at the four photos shown below. Each of the photos is shown on four different screen monitors. Note how different the colors look on the monitors. Before color management is implemented on the four devices, there are visible color differences due to varying hardware technologies and color settings. The default color settings, for example, color temperature, saturation and contrast, you find on your home’s display will generally cater to the color needs of typical use. However, for commercial printing companies and for freelancers and professionals whose work requires color precision, color management becomes essential in their workflow.
Designers such as graphic designers, multimedia designers, web designers and other creative professionals who create visual concepts by using computer software need color management. Color management can help these creative professionals communicate their ideas better and more effectively. Done properly, each device in their workflow will reproduce consistent colors.
