We're looking to launch a new version of a website, and we had multiple users concerned about readability with grey text on a grey background.
I did some basic search, and found this website. Using ColorZilla for Chrome, I obtained #EFEFF4 for background color, and #A7A7AB for foreground color, for a contrast ratio of 2.06-2.1 depending on where I pick the foreground color.
Is this the correct way to measure contrast?
Are there any good accessbility documents that I can send to the developer? I found the WCAG 2.0 guide, but is there anything a bit more friendly if I need to bring this up in a discussion?
