It could show the picked color as a reference. Could pick all the back and forground colors and show the results according to that while checking the entire website.
Very good! Love the recommendation's also!
Very useful tool! And easy to use.
Finally. After installing 7-8 extension this is the only one that appears to a) do something; b) have instructions and support, c) actually provide some assistance with determining whether I can safely state my foreground text is of high enough contrast with the background image. Well done.
Stellar extension, fluidic UI/UX. Highly recommended to all the accessibility practitioners out there.
This tool is fantastic; as an accessibility tester, I really depend on it to suggest colours to clients because it saves so much time in locating hues that meet the necessary contrast ratio. Overall, I had a good experience using this tool and am eagerly awaiting new updates and features.
Amusing tool! Highly recommended. It will save time
Really great experience using this tool, this saves lots of time by showing recommendations and yes that a best part of having recommendations and color shades, keep updating.
