On the screen of a color television or computer, white is produced by mixing the primary colors of light: red, green and blue at full intensity, a process called additive mixing (see image above). White light can be fabricated using light with only two wavelengths, for instance by mixing light from a red and cyan laser or yellow and blue lasers.
An achromatic white is a white color in which the red, green, and blues codes are exactly equal. The web colors white and white smoke are achromatic colors. A chromatic shade of white is a white color in which the red, green, and blue codes are not exactly equal, but are close to each other, which is what makes it a shade of white.

CMYK is used in the printing process, because it describes what kinds of inks are needed to be applied so the light reflected from the substrate and through the inks produces a given color. One starts with a white substrate (canvas, page, etc.), and uses ink to subtract color from white to create an image.
Poor-quality images—dark or blurry; showing the subject too small, hidden in clutter, or ambiguous; and so on—should not be used unless absolutely necessary. Think carefully about which images best illustrate the subject matter. For example: An image of a white-tailed eagle is useless if the bird appears as a speck in the sky.
Example of color balancing. Sometimes the adjustment to keep neutrals neutral is called white balance, and the phrase color balance refers to the adjustment that in addition makes other colors in a displayed image appear to have the same general appearance as the colors in an original scene. [4]
A white point (often referred to as reference white or target white in technical documents) is a set of tristimulus values or chromaticity coordinates that serve to define the color "white" in image capture, encoding, or reproduction. [1] Depending on the application, different definitions of white are needed to give acceptable results.
