Map or Drawing Tool Controls With Too-Low Contrast
1.4.11 — Non-text Contrast
Scenario
Setting
A recipe site's ingredient list
What’s wrong
Map controls / drawing tools where required visual info fails ratio.
Example
A recipe site's ingredient list runs into this exact issue: map controls / drawing tools where required visual info fails ratio.
Why it matters
Low-vision and color-blind people who need to perceive controls and meaningful graphics. On a recipe site's ingredient list, this barrier means they can't perceive part of the content because of how it's displayed.
How to test
Measure map controls and drawing-tool icons against their background: 3:1 minimum where they convey required information.
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
Corrected, a recipe site's ingredient list now lets a visitor see the control's boundary and current state.
Who is affected
Low-vision and color-blind people who need to perceive controls and meaningful graphics.
