Sip includes support for simulating how colors appear to people with different types of color vision deficiencies. 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.
