Information (provided by colour)

This term is defined by more than one standard, and the wording differs. Each definition below is the one that applies to that standard’s criteria.

Definition in RAWeb 1.1

Information conveyed visually through colour. The indication that fields in red are mandatory in a form, the use of a blue background to indicate the page currently being consulted in a menu with a green background, the change of colour of an item name to indicate its unavailability in a list of items are all examples of information given by colour.

When information (provided by colour) is accompanied by another method aimed at users who cannot see or perceive colours or their associations well, the criterion will be considered as not applicable.

Means of conveying information other than by colour may be

  • A visible text indication;
  • Means involving graphics (pictogram, background image, shape, different border style, etc.) and through a complement to the code (aria-label, title, hidden text, aria-current, etc.);
  • A different typographic style (bold, italic, text size, different font, etc.) and by means of a supplement in the code (aria-label, title, hidden text, aria-current, etc.).

Definition in RAAM 1.1

Information transmitted visually by means of a colour. The indication that fields in red are mandatory in a form, the active button in a list of buttons, the change of colour of an item name to indicate its unavailability in a list of items are all examples of information given by colour.

Indication by colour alone must be accompanied by another method for users who do not see or perceive colours or their associations well.

The indication given by colour must be provided:

  • by a means involving graphics (pictogram, background image, shape, different border style, etc.) or another typographic style (bold, italic, text size, other font, etc.) for users with limited colour perception.
  • and by descriptive (non-visible) information present on the element so that screen readers can render the information to users who cannot see.
