G14: Ensuring that information conveyed by color differences is also available in text

Applicability

All technologies that support color and text.

This technique relates to:

Description

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.

Examples

Example 1: A color-coded schedule

The schedule for sessions at a technology conference is organized into three tracks. Sessions for Track 1 are displayed over a blue background. Sessions in Track 2 are displayed over a yellow background. Sessions in Track 3 are displayed on a green background. After the name of each session is a code identifying the track in text: T1 for Track 1, T2 for Track 2, and T3 for Track 3.

Example 2: A color-coded schedule with icons

The schedule for sessions at a technology conference is organized into three tracks. Next to the title of each session is a colored icon showing what track it belongs to: blue icons represent track 1, yellow icons represent Track 2, and green icons represent Track 3. Each icon is associated with a text alternative reading "Track 1," "Track 2," or "Track 3," as appropriate.

Example 3: A table showing the conference schedule

The schedule for sessions at a technology conference is organized into three tracks. The schedule for each day is shown in a data table with headers for Time, Title, and Track. Sessions for Track 1 are displayed over a blue background. Sessions in Track 2 are displayed over a yellow background. Sessions in Track 3 are displayed on a green background.

Example 4: A form with required fields

A form contains several required fields. The labels for the required fields are displayed in red. In addition, at the end of each label is an asterisk character, *. The instructions for completing the form indicate that "all required fields are displayed in red and marked with an asterisk *", followed by an example.

Example 5: A form with a green submit button

An on-line loan application explains that green buttons advance in the process and red buttons cancel the process. A form contains a green button containing the text Go. The instructions say "Press the button labeled Go to submit your results and proceed to the next step."
