Chrome Color Contrast Analyzer


From: Joseph Sherman
Date: Aug 25, 2016 1:35PM

I like two tools: For web pages I like the color checker in html CodeSniffer<http://squizlabs.github.io/HTML_CodeSniffer/>;, largely because it gives suggestions for text or background color that will meet the spec.

For checking individual elements I like the color contrast analyzer<http://www.paciellogroup.com/resources/contrast-analyser.html>; since you can select the pixels to compare.

Among others, there’s also the WCAG color contrast add-in for FireFox, Juicy Studio Toolbar, and (un)clrd for Chrome which shows the page in black and white.
