Ghost Button on a Photo With Contrast Below the Minimum
1.4.11 — Non-text Contrast
Scenario
Setting
A survey tool's question builder
What’s wrong
Ghost/outline buttons on hero images falling below 3:1.
Example
Picture a survey tool's question builder: ghost/outline buttons on hero images falling below 3:1.
Why it matters
Low-vision and color-blind people who need to perceive controls and meaningful graphics. In this case (a survey tool's question builder), they can't read the text against its background.
How to test
Measure a ghost/outline button's border against the hero image or photo behind it at its lowest-contrast point: 3:1 minimum.
How to fix
The visual element (border, icon, indicator, state marker) must have at least 3:1 contrast against adjacent colors in every state.
Outcome
Once corrected, a survey tool's question builder lets them tell the information apart without relying on color.
Who is affected
Low-vision and color-blind people who need to perceive controls and meaningful graphics.
