- (2023-09-11) John Doe: Good, but I would've loved RGB values too, and a comparison between each of the RGB values
- (2023-04-11) Pablo Alvar mcv: muy útil y muy buen diseño. Enhorabuena y gracias!
- (2023-01-09) Lino Buzy: perfect
- (2022-12-08) Brad Chapman: Didn't work.
- (2022-08-18) Christian Kodehode: Edit: Initially this extension refused to activate after I installed it. However, once I went into my browser's extensions settings and opened the details for this extension where I manually enabled access to file URLs (this was disabled by default) and then restarted my browser, it started working. The same solution applies to similar extensions I tested, and this works on both Chrome and Vivaldi.
- (2022-06-24) Aesha Patel: I figured it out, open the link, and then hold the click on the extension for 2 s. and it will pop down.
- (2022-06-21) Saarah Anne Fletcher: No matter how many times I refreshed or clicked, nothing happened. A bit because it's so pretty.
- (2022-06-20) Samali: Very simple, Does the job really well
- (2021-06-28) Gabrielle: Simple & effective. Use this tool on the daily. Thanks for developing!
- (2021-04-15) Sophie Bryson: Technically, it works. But there is no explanation of the pass/fail results which makes this not appropriate to recommend to my non-tech savvy coworkers who need to test color contrast.
- (2021-03-04) Michael Harshbarger: Great tool to check colour contrast within your browser! Thanks Alex,
- (2021-02-24) Amara Eddins: Really wanted to try this tool, but I updated chrome, checked the extension was up to date, restarted my computer, forced quit chrome. Everything, just wouldn't work me, super disappointed and wasted some important work time. Maybe in the future I can try it again and give a more positive review.
- (2020-12-31) anonymous: Thank you so much for developing this extension. This helps me a lot.
- (2020-08-06) Amy Collins: I really like this idea but I wish it worked for while I was developing websites offline.
- (2020-07-30) Johannes Grandy: 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).

- (2019-10-28) Josh V: 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.
- (2019-10-10) Lou Knowles PM: 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
