Thank you so much for developing this extension. This helps me a lot.
I really like this idea but I wish it worked for while I was developing websites offline.
Actually this is a pretty good contrast checker. Definitely the best i've used so far. A few things could be better: - When clicking on the pipette for picking a color, it takes 1-2 seconds to load. Actually this is the point that annoys me the most. Would be great if that loads instantly. - In the top right are three action buttons that are cut on my computer. Don't know if that is a problem with my system or a general one. Should be investigated on. - The fail/pass badges a a bit to subtle for my opinion. Especially when modifying the color it would be nice to have a more prominent feedback (maybe failing is outlined and passing is solid color).
Great tool!
love it
Fab little extension, does everything a designer could need for creating accessible online experiences. (Particularly love the eye dropper feature!)
What a breath of fresh air, an actually usable contrast checker. The author obviously put thought into the design and it's a delight to use.
Its great for Dev's and QA's for ensuring that your colours on your pages are AA or AAA compliant with accessibility standards. Love the new colour picker feature too
Invaluable for real devs.
Fantastic tool for developers!
