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 in Figure 204 shows good and bad contrasts.

Good contrast

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 of bright colors to show feedback.

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.
