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 :(
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.
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.
Не работает, нажимаю на разрешение, нажимаю режим, но не работает :(
Its not working for any website on chrome Version 84.0.4147.125 (Official Build) (64-bit)
If you are a designer, YOU NEED THIS EXTENSION. It's simply brilliant. Bless the developer for creating this tool.
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.
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.
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.
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!
