Selected-State Marker Too Faint to Notice
1.4.11 — Non-text Contrast
Scenario
Setting
A crowdfunding platform's campaign page
What’s wrong
Selected-state indication (tab underline, active card border) <3:1.
Example
A crowdfunding platform's campaign page is a good example: selected-state indication (tab underline, active card border) <3:1.
Why it matters
Low-vision and color-blind people who need to perceive controls and meaningful graphics. On a crowdfunding platform's campaign page, that means they miss information conveyed only by color.
How to test
Measure the visual marker for a selected state (tab underline, active card border) against its background: 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
With the fix in place on a crowdfunding platform's campaign page, they 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.
