Functional Outcome

The track information is available from the icon's text alternative.

Technical Comment

The information which track the session belongs to is available from the icon's colour and the img element's alt attribute. But the colour coding is not simultaneously visually evident without the colour.

This test case maps to technique G14: Ensuring that color-encoded information is also available in text. (See example 2: A color-coded schedule with icons. However, the test procedure requires that the text is not conditional content (in other words, not alt text.)
