The color modes and color models of digital imaging seem to be a bit of an enigma to those first experiencing Photoshop. The diversity of color modes can be so overwhelming that novice users many times avoid these features without realizing the impact color modes can have on the end results of the image.
The color modes establish the color model that should be applied to display and print digital pictures. Understanding color modes and models and how to utilize them in Photoshop is a must for those who are serious about professional quality digital imaging. Learn what color modes will work best for different application to optimize results. Many good Photoshop tutorials and training guides are available to instruct on when and how to use the various color modes for achieving the best image depending on your particular project.
But what exactly are color modes and why are there different models? Let's take a moment to learn the basic color modes in Photoshop and how they work.
Several different color modes are used to display digital images. Here is a brief overview of the main basic color modes you will come across when working with digital images.
RGB
RGB stands for Red Green and Blue. Colors in RGB color mode are generated using a combination of these three primary colors. You basically have three color channels to work with in RGB mode with the ability to adjust the intensity of each channel to produce different degrees of colors. Combine all three of the colors to create white.
CMYK
CMYK stands for cyan, magenta, yellow and black. RGB produces colors by mixing them together, while CMYK in effect creates color by subtracting varying degrees of each color. For example, to produce white, all colors would be reduced to zero.
You will see huge improvements in your digital imaging once you understand and are familiar with color modes. One important tip is that printers use CMYK color while monitors use RGB. This can result in there sometimes being a difference in what you see on your PC monitor and what is printed on paper. You can overcome this by installing software that will calibrate your monitor colors to that of your printer. By doing this, what you see on your monitor will be an accurate depiction of what your printer will produce.
