1.5-14 Display Background Color

A uniform nondistracting background color should be used with a hue/contrast that allows the data (foreground) to be easily visible and which does not distort or interfere with the coding aspects of the display.

Additional Information:
Patterned backgrounds should be avoided. Background color can influence the way a user perceives a color symbol (e.g., shapes and lines). When a color is surrounded by another color, the surrounding color can change the appearance of the enclosed color. For example, green on a yellow background will appear more blue than the same shade of green on a blue background. Different colored backgrounds may be used as a coding method to meaningfully group information, provided that colors are chosen to maintain good contrast and legibility.
