Input Field Border With Contrast Too Low to See

1.4.11 — Non-text Contrast

Scenario

Setting

A pharmacy app's prescription-refill form

What’s wrong

Input borders below 3:1 against adjacent background (light grey #ccc on white) with no other boundary cue where boundary is required to identify the control.

Example

border: 1px solid #dcdcdc; /* icon outline, ~1.2:1 against white */

Why it matters

Low-vision and color-blind people who need to perceive controls and meaningful graphics.

How to test

Measure an input field's border color against its background with a contrast checker: it needs at least 3:1 (common failure: light grey #ccc borders on white).

How to fix

The visual element (border, icon, indicator, state marker) must have at least 3:1 contrast against adjacent colors in every state. border: 1px solid #767676; /* ~4.5:1 */ Icons, borders, and other non-text UI elements need at least 3:1 contrast to stay visible.

Outcome

On a pharmacy app's prescription-refill form, this barrier is gone for low-vision and color-blind people who need to perceive controls and meaningful graphics — they no longer have to work around this.
