Eric Bonar (ID: 0000008f4d7052f6) Voted 5 ★ - Updated 02/22/2023 I like the ease of use and how straight forward it is. I can easily copy and paste HEX codes into the different sections, or use the eyedropper to grab the color I need. An issue with the eyedropper is that it's zoomed in so much that it can be a little difficult to get on a row or column of pixels in order to grab the color you're trying to get. I tried it on the menu of my client's site and the pixels it showed for the text were various colors (I'll comment with a screenshot). I typically use ColorZilla to grab color codes, but it's zoom is not as good as yours. Having the iframe take up space at the top of the window, and not being able to adjust the height of it will take a little getting used to. This is not a complaint, btw. I appreciate that you included a "More color details" section that can expand to show the wcag color levels chart for the text color, and the various colors within that range below the chart. That makes it so much easier to decide which color to use. Overall, GREAT JOB! This is going to be the one I use for testing from now on.
