• Avoid using adjacent colors or background shades. When you use the same
colors or shades, the objects or text may be hard to see or read. The example

• Do not use bright or intense colors for buttons that display for long periods
of time. The brighter the colors, the more fatiguing to the eyes. Limit the use

• If you use a graphic on a button, either make the button the same as the
background on the graphic or change the background color of the graphic to
match the button.
