ColorCheker

ColorCheker helps you design more accessible experiences by instantly checking color combinations.

Pick any color using the built-in color picker or sample directly from your screen with the eyedropper tool. ColorCheker calculates the ratio in real time and tells you whether your combination passes AA or AAA compliance.

See your colors in action before you ship. ColorCheker previews how real UI components like buttons, cards, text, and inputs  look with your chosen color pair, so you can make confident design decisions without leaving the app.

Understand how your palette looks to everyone. Built-in color blindness filters simulate how people with deuteranopia, protanopia, tritanopia and greyscale perceive your colors, helping you design for the full spectrum of human vision
