Complete color blindness (rare)
This tool helps designers, developers, and content creators ensure their work is accessible to people with different types of color vision deficiencies. By simulating how your colors and images appear to color blind users, you can make informed decisions to improve accessibility.
Frequently Asked Questions
What is color blindness?
Color blindness (color vision deficiency) is the decreased ability to see color or differences in color. It can impair tasks such as selecting ripe fruit, choosing clothing, and reading traffic lights.
How accurate is this simulator?
Our simulator uses scientifically validated algorithms to approximate how colors appear to people with different types of color vision deficiencies. While it provides a close approximation, individual experiences may vary.
How can I design for color blind users?
Use high contrast between text and background, avoid color-only indicators (use text or icons too), and test your designs with color blindness simulators. Also consider patterns or textures in addition to colors.
Can color blindness be cured?
Currently, there is no cure for inherited color blindness. However, special glasses and contact lenses are available that can help some people distinguish between certain colors better under specific lighting conditions.
