Introduction
This module will discuss user-selectable display settings, including contrast and color, and provide methods of testing to be certain these settings are not disabled by an application.
The Section 508 requirement covering this is: §1194.21 (g) Applications shall not override user selected contrast and color selections and other individual display attributes.
Application functions must not disable or change user-selected display settings. Users with low vision or color blindness may only be able to see certain color combinations or they may work most efficiently with specific color and/or contrast settings. When an application disables these settings, the product becomes less accessible, and some people may not be able to use it at all.
Remember, both testers and developers can use the checkpoints for this requirement to be sure the products they are working with will be accessible to users with disabilities, including those using assistive technology (AT).
Use the link above to look at the checkpoints now. You may wish to keep the window open as a reference to use as you complete this module.
