Placeholder Text With Contrast Too Low to Read Easily

1.4.3 — Contrast (Minimum)

Scenario

Setting

A calendar app's event-creation form

What’s wrong

Placeholder text below 4.5:1 (it's still text content users must read).

Example

On a calendar app's event-creation form: placeholder text below 4.5:1 (it's still text content users must read).

Why it matters

Low-vision and older readers, plus anyone viewing a dim or sunlit screen. The practical effect on a calendar app's event-creation form: they can't perceive the control's boundary or state.

How to test

Click into an empty input and measure the placeholder text's contrast against the field background: it needs at least 4.5:1, same as normal text.

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

That one change on a calendar app's event-creation form means they read the text clearly against its background.

Who is affected

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