Andrew Somers (ID: 000000006fda514c) Voted 5 ★ - Updated 07/26/2023 Good. This is the first extension I've seen that uses the proper Brettel model for deuteranopia & protanopia. Most of the other simulators out there are substantially incorrect. Designers should look at the protanopia simulation in particular, to ensure that their designs are accessible and readable.

Yury Sitnikov (ID: 000000322c33d222) Voted 5 ★ - Updated 06/16/2023 Just started to use the extension, and I see my site exactly as several real people with different types of color blindness described it, and now I understand what they mean and how to fix it. Very useful tool!

Diana Grappasonno (ID: 000000ee90e65864) Voted 5 ★ - Updated 02/06/2023 Works great for me! Using an older version of Chrome on an old Mac.
