Selected Tab or Item Text Failing the Contrast Minimum

1.4.3 — Contrast (Minimum)

Scenario

Setting

A job board's application form

What’s wrong

Selected/current item text (e.g., active tab white-on-light-blue) failing.

Example

color: #999999; background: #ffffff; /* 2.85:1 */

Why it matters

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

How to test

Measure the currently selected item (active tab, chosen filter) against its own highlighted background — selection styling often drops contrast below default state.

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). color: #595959; background: #ffffff; /* 7:1 */ Normal text needs at least 4.5:1 contrast against its background; large text needs at least 3:1.

Outcome

On a job board's application form, this barrier is gone for low-vision and older readers — they get the same result as anyone else here.

Who is affected

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