Issues

Control Panel Buttons (2 of 11)

Issue: Buttons that do not have sufficient contrast with the panel are difficult for users with low vision to detect.

A numeric keypad and other control panel buttons are shown.  The buttons are gray on a gray background, and therefore have very little contrast with the background.

If buttons are the same color as the control panel, they may blend in with the panel, making it difficult for a user with low vision to distinguish the button from the surrounding surface.

Populations Impacted: Users with low vision.

Potential Solution:
  • Ensure that buttons are different in color from the control panel surface. Buttons should be colored differently from the control panel, making them easy for a low vision user to distinguish. Using sufficiently contrasting colors will aid users in distinguishing buttons from one another. For example, a bright green "Enter" button would be easily distinguishable from a dark gray control panel. Backlighting buttons may also help distinguish them from the surrounding surface.

  • A numeric keypad and other control panel buttons are shown.  The buttons are colored blue, green, yellow, and red on a gray background, and therefore have good contrast with the background.
