Why designers use it
- Check UI mockups to ensure contrast and iconography remain clear for colour-blind users.
- Evaluate marketing graphics before publishing so no information is lost.
- Educate teams about accessibility by comparing normal and simulated views side by side.
Tips
- Provide text labels or patterns in addition to colour to communicate status.
- Download example outputs to include in accessibility audits or design review docs.
- Test multiple deficiency modes—users may experience partial or full colour loss.
