Designing with Color Accessibility in Mind

Around 1 in 12 men and 1 in 200 women experience some form of color vision deficiency. Yet, many designs still rely heavily on color to convey meaning. This simulator lets you step into the shoes of a colorblind user and adjust your palette accordingly.

Whether you're creating a website, branding materials, UI interface, or infographics, color contrast and distinguishability matter. Poor color accessibility leads to misinterpretation, frustration, and exclusion. This tool empowers you to test and adapt before your content goes live.

How It Works

Simply upload an image or use the built-in palette of six core colors. Choose between four filters: Normal, Protanopia, Deuteranopia, or Tritanopia. The preview panel updates live with an SVG filter that adjusts the visual spectrum to reflect each deficiency’s impact.

Why It Matters
