Star Rating Icons Where Filled and Empty Look Too Similar
1.4.11 — Non-text Contrast
Scenario
Setting
A car-rental site's checkout flow
What’s wrong
Star/rating icons where filled vs — unfilled distinction <3:1.
Example
This shows up on a car-rental site's checkout flow: star/rating icons where filled vs — unfilled distinction <3:1.
Why it matters
Low-vision and color-blind people who need to perceive controls and meaningful graphics. In this case (a car-rental site's checkout flow), they can't perceive part of the content because of how it's displayed.
How to test
Measure the difference between filled and unfilled star icons in a rating widget: below 3:1 makes the current rating unreadable.
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 car-rental site's checkout flow lets them tell the information apart without relying on color, specifically for the “Star Rating Icons Where Filled and Empty Look Too Similar” issue on a car-rental site's checkout flow.
Who is affected
Low-vision and color-blind people who need to perceive controls and meaningful graphics.
