Low-Contrast Text Hiding in Dropdowns, Toasts, and Chips

1.4.3 — Contrast (Minimum)

Scenario

Setting

A budget airline's flight search results

What’s wrong

Text in <option>s, tooltips, toasts, badges, chips overlooked in audits and failing.

Example

This shows up on a budget airline's flight search results: text in <option>s, tooltips, toasts, badges, chips overlooked in audits and failing.

Why it matters

Low-vision and older readers, plus anyone viewing a dim or sunlit screen. In this case (a budget airline's flight search results), they can't perceive part of the content because of how it's displayed.

How to test

Measure text inside dropdown options, tooltips, toast notifications, badges, and chips specifically — these are commonly skipped in audits.

How to fix

The text must meet at least 4.5:1 contrast (3:1 for large text) against its actual background in every state (default, hover, focus, selected).

Outcome

Once corrected, a budget airline's flight search results lets them tell the information apart without relying on color.

Who is affected

Low-vision and older readers, plus anyone viewing a dim or sunlit screen.
