• (2023-07-26) Andrew Somers: 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.
• (2023-06-16) Yury Sitnikov: 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!
• (2023-05-15) Anne White: i killed a bear in a fist fight
• (2023-02-06) Diana Grappasonno: Works great for me! Using an older version of Chrome on an old Mac.
• (2023-01-30) Kayla VanNess: This extension changed me and my cats life forever.
• (2022-09-29) Pontus: Super handy tool for checking accessibility when designing and developing sites. It has helped me explain to customers why colorblind accessibility is important when designing a website.
• (2022-08-03) UltraLuigi2401: Amazing
• (2022-07-25) Danielle Timcke: Installed and pinned the extension. But upon trying it (on lots of different websites) it doesn't do anything... I've refreshed but still nothing on any of the colour blind settings. Wish this worked because it would be so useful :(
• (2022-07-17) Kalamatize Games: It didnt work what so ever. Can you please notify me on how to use it because ive done everything im meant to do
• (2022-07-12) Alex: Works great, using it on windows 10 64-bit and there's no problems
• (2022-03-26) Rene van der Lende: Nice tool, doesn't work on locally opened pages on Windows 10-x64 making it less useful for web development.
• (2022-02-02) Sofía M: Doesn't work at all, I tried with different websites, what is it supposed to do? I've clicked on everything and it doesn't change a single color :(
• (2021-07-20) Tomas Beblar: Works as advertised. Not sure why other users are having issues getting it to run but for me it was as simple as installing, clicking the extension icon, and selecting a mode. Kudos for a great extension.
• (2021-05-18) Zachary Bunch: Thank you, thank you, thank you! Works well for my color coded college material!
• (2021-02-10) Joshua Hargrave: I've put a middling review as I don't know how good it is as I've got it but I can't work out how or where to make it actually do the colourblindness.
• (2020-12-31) Titigo: Не работает, нажимаю на разрешение, нажимаю режим, но не работает :(
• (2020-10-05) I don't even have the icon in the extensions menu.
• (2020-08-12) Vinita Atre: Its not working for any website on chrome Version 84.0.4147.125 (Official Build) (64-bit)
• (2020-07-24) Kimberli Kelmor (Kimberli Morris Kelmor): I was happy to find this extension. Unfortunately it doesn't work at all. Something must have updated in Chrome that broke it. I hope the developer updates it so it works again!
• (2020-04-01) Clifton Long Jr.: If you are a designer, YOU NEED THIS EXTENSION. It's simply brilliant. Bless the developer for creating this tool.
• (2020-02-21) Daniel Ziga: Perfect extension for colorblindness. Have only used this for a for days and I love it. Probably the best extension for web development in regards of accessibility.
• (2020-02-15) Not Hax (DavidZar): Literally doesn't work what so ever, I click one of them and it doesn't change anything. It might just be that it hasn't been updated, but I guess I'll have to change my review after it is.
• (2020-01-09) Hal Caliver: This is a great app. It's important that designers and developers make efforts to make online spaces more accessible and accommodating. This tool helps them do just that. The UI is easy to use and not over designed. Good stuff.
• (2019-12-20) Tabbatha Crouch: This is an absolutely wonderful tool! My entire curriculum/content development team now uses this chrome extension to help us meet our accessibility needs. Thank you so much for creating such a useful and user friendly tool!
• (2019-11-30) かりんとう: 色弱の日本人です。 この拡張機能を使用して色弱テストを試しにやってみると、 絶対にこうだと思っていたものが完全に覆されました... いい体験をさせていただいたということで今回は星5にさせていただきました。 Thank you for make plugin !!
• (2019-09-01) Luna Lucadou: Most of the other extensions I found manage to really mess up the page layout or only include the most common types (Tritanopia, Deuteranopia, and Protanopia). This simulates 8 types and doesn't seem to destroy page layouts. This is a great extension, I highly recommend it.
• (2018-12-06) Brad Cooper: Amazing! Exactly what I needed for this new web application that I'm working on!
• (2018-10-15) Connor: A lovely little extension to use. Very interesting even if you're not trying to maximize accessibility for your site. I know nothing about colorblindness, so I can't make a judgement as to the "accuracy" of the various types of colorblindness you can set, but to my untrained eye (hah!) it looks fairly comprehensive. Great work!
