les mondes de la couleur, les couleurs du monde Base de bons et mauvais exemples JuicyStudio Colour Contrast The old Accessibility Evaluation and Repair Tools (AERT) suggested algorithm for determining colour contrast now directs here. The AERT algorithm was never a recommendation, and WCAG 2.0's luminosity contrast algorithm is recommended instead. Success Criterion 1.4.3 of WCAG 2.0 requires the visual presentation of text and images of text has a contrast ratio of at least 4.5:1, except for the following: Large Text: Large-scale text and images of large-scale text have a contrast ratio of at least 3:1; Incidental: Text or images of text that are part of an inactive user interface component, that are pure decoration, that are not visible to anyone, or that are part of a picture that contains significant other visual content, have no contrast requirement.

CSS Colors: MintCream, HoneyDew, & PeachPuff • Pugly Pixel Overcast and cloudy, or rather, "Mostly Cloudy," is the forecast that I pray for as I squint into my iPhone weather app at 5:30 every morning. But, just my luck, I usually get "Sunny" or "Partly Cloudy", which usually turns out to be "Mostly Sunny". Oh, but not so today, my friends. Today I got "Rain" --- glorious afternoon rain!

Myths About How Blind People Use the Internet As a frontend developer of course I’d heard about accessibility. I’d always followed best practices when creating web content that shouldn’t have any problems being read by a screenreader. Like so many other developers in my position though I’d never actually tried a screenreader myself. It always seemed like a difficult thing to do, and I’d heard it was expensive. Myth: Screenreaders Read Link Title Text This is not true, and surprised me greatly! @silktide says: We’re researching link title text, & how it’s not used by screen readers. @Zeldman says: No! I wrote more about how I mistakenly thought title text improved accessibility here. Myth: Blind Users Use a Text-Only Browser Don’t get confused between a screenreader and a browser, they aren’t the same. According to a study by WebAIM the majority of screenreader users use Internet Explorer and Firefox on Windows. Myth: Blind Users Don’t Have JavaScript Enabled How many users of any kind actually disable JavaScript? Summary

RGBA Calculator How we all see colors differently—Color theory in design | Koos Looijesteijn There’s the old question: “Do you see that color the same way I see it in my mind?” To some extend this will remain a philosophical question involving the swapping of hypothetical consciousnesses between hypothetical brains. But here’s what we do know. Three reasons why people looking at one thing can see something differently 1) Cone sensitivity differs between people Cones are the cells on your retina sensing light in one of three color ranges. Sensitivity can also differ greatly from person to person. 2) Vision changes constantly Even an individual can perceive one color differently depending on the context. Time doesn’t even have to be involved. In lab experiments on researchers got people to classify colors as blue that they called purple just minutes earlier. 3) Culture defines how we see color There’s a whole cultural processing layer defining what colors we’re able to see. Depending on where children grow up, they learn different words to label colors. There's no blue in Russian.

There’s already a blueprint for a more accessible internet. The internet can be a hostile space for 15% of the world’s population who experience some form of disability. Try navigating a website as someone who is visually impaired: Turn on voice command on your computer (Command ⌘ + F5 if you’re on a Mac, enable Navigator if you’re on a PC) and go to Amazon’s Kindle store. You’ll quickly find out that those who rely on voice commands can’t skip around and are doomed to listen to every notation about every page element before getting to the one piece of information they need. “It’s a crime that the most versatile device on the planet—the computer—has not adapted well to people who need help,” laments Vint Cerf, the “father of the internet,” who co-authored the net’s communication protocol with Bob Kahn. The 75-year old computer scientist knows this pain point first hand having been born with a hearing impairment and color blindness. The internet was a welcoming place when Cerf conceived of it. Some recommendations are less obvious. Quartz
