With a single toggle, you can preview your palettes through the lens of: * **Normal** – Standard color perception * **Protanopia** – Red-weak vision * **Deuteranopia** – Green-weak vision * **Tritanopia** – Blue-yellow color blindness * **Achromatopsia** – Total color blindness (no color perception) ## Why This Matters Color blindness affects over 300 million people worldwide. With this feature, you can: * Instantly simulate different types of color vision * Validate accessibility in your designs * Ensure your palettes are inclusive and legible for everyone Whether you're a designer, developer, or accessibility advocate, this tool helps you build more inclusive visuals in Sip. You'll find the simulation modes in the **Color Blindness** control in the bottom bar. Pick one to see your palettes transform in real time. ## Change Color Blindness Mode from the Menu Use the **Color Blindness** control in the bottom bar to switch between Normal, Protanopia, Deuteranopia, Tritanopia, and Achromatopsia. color-blindness-menu color-blindness-menu ## Change Color Blindness Mode from the Main Window In the Main Window, use the **Color Blindness** control in the bottom bar to preview how your colors appear to users with different types of vision. color-blindness-main color-blindness-main ## See Color Blindness Preview in the Picker When you select a simulation mode, the Color Picker updates in real time to reflect the chosen mode, such as Tritanopia.
