aidColors: Free Color Blindness Simulator & Accessibility Tool

A free online tool to simulate color blindness, test website designs for accessibility, and ensure inclusive digital experiences

What is AidColors?

aidColors is a free online tool that helps designers and developers test websites for color vision deficiency issues. It can simulate various types of color blindness including protanopia, deuteranopia, tritanopia, and more. The tool allows you to enter a URL or upload images to preview how those with color vision deficiencies would perceive that content. You can then make adjustments to improve accessibility and optimize for those users.

aidColors is useful both for testing existing sites as well as checking designs during the development process. By seeing how those with deficiencies like red-green and blue-yellow color blindness would see your site, you can identify problem areas like insufficient contrast, reliance solely on color to convey meaning, and loss of visual hierarchy. Simulating these views allows you to address such issues early on. The tool helps you ensure your site offers a good experience regardless of a user's ability to perceive color.

In additional to offering simulations of different types of color blindness, aidColors provides resources and guidelines for designing accessible sites for those with deficiencies. This includes suggested color palettes, tips for choosing accessible colors, instructional videos, and an ebook covering best practices. The tool also enables batch processing so you can check multiple pages for issues. The service is available through a free online interface requiring no account setup or software downloads.
