Hi all, Maybe this wording will do it. When the content author uses visual cues to guide the visual use’s visual scanning of the page, a user with reduced contrast sensitivity should be able to perceive the visual cues being used. Specifically, all such visual cures must provide sufficient contrast to support detection by users with reduced contrast sensitivity. Explanation: Often form fields and special blocks of text like definition or navigation sections are called out using borders or changes in background color. In these cases, the borders and altered background colors should provide sufficient contrast with the all adjacent regions of the page. This includes all borders used for form fields, radio buttons, check boxes and focus indicators. Objects that are distinguished by alternative colors including form fields should also have sufficient contrast as defined in the WCAG 2.0 glossary.
