The objective of this technique is to ensure that when color differences are used to convey information, such as required form fields, the information conveyed by the color differences are also conveyed explicitly in text.
The schedule for sessions at a technology conference is organized into three tracks. Sessions for Track 1 are displayed over a blue background.
