An interesting, in-depth look by University of Cambridge’s Inclusive Design Tools Group at the W3C WAI Web Content #Accessibility Guidelines (#WCAG) contrast formula and proposed changes based on the Advanced Perceptual Contrast Algorithm (#APCA).


Hi, I'm a web & UX librarian at Carleton University in Ottawa. I like the web side of things, but my main interest is UX. I will always make time to chat about UX with other academic librarians; happy to be a sounding board or cheerleader.

I've fallen into the habit of being more of a reader/lurker than a poster, but will try to be better about the social part of social media :)
