FAQ Frequently Asked Questions

What types of color blindness can be simulated?
The simulator typically covers the main types including Protanopia (red-blind), Deuteranopia (green-blind), Tritanopia (blue-blind), and sometimes Achromatopsia (complete color blindness). These cover the vast majority of color vision deficiencies.
How accurate are the color blindness simulations?
Simulations provide good approximations of color vision deficiencies, but individual experiences vary. The simulations help identify potential accessibility issues, though testing with actual color-blind users is always recommended.
Can I test entire websites or just images?
Many tools can simulate color blindness effects on entire webpages, not just individual images. This helps evaluate overall website accessibility including text, buttons, links, and interface elements.
What should I look for when testing my designs?
Check that important information isn't conveyed by color alone, ensure sufficient contrast between text and backgrounds, verify that interactive elements remain distinguishable, and confirm that error messages are understandable.
Is this sufficient for accessibility compliance?
Color blindness simulation is one important accessibility test, but comprehensive compliance requires additional testing including screen readers, keyboard navigation, and other accessibility guidelines like WCAG standards.
