Web Accessibility |
CofC Web Accessibility Guidelines- Rule (C)(c) Web pages shall be designed so that all information conveyed with color is also available without color, for example from context or markup. Translation: Make sure that color alone is not used to identify information. For example, an instruction such as "click on the orange items for more information " uses only color to identify the items which may be selected. apple What to do: Do not use color as the sole means to identify an item on a page. To make the example above accessible, use an alternative means of identification like "select the underlined items" or "select the items indicated by *."
apple If this is not possible, provide a text-only version of the page. See rule (k) for some notes about maintaining duplicate text pages. Appropriate use of descriptive text is the best solution. Quick Check: There are a couple of ways to see if the color contrast on your pages is sufficient to be read by people with color deficiencies or by those with low resolution monitors. One method is to print pages on a black and white printer (with backgrounds and colors appearing in grayscale). Another method is to take a screen shot of the page in question, open it in a photo editing program, and change it to greyscale. This will help you identify items which will not be clear to those with color disabilities. |
