Finding the Right Color Palettes for Data Visualizations

To make sure color palettes are extremely accessible and easy to distinguish, they must vary enough in brightness. Differences in brightness are universal. Take any monochromatic color palette and test how it looks in Protanopia, Deuteranopia, and grayscale mode. You’ll quickly be able to tell how accessible this palette is.

From a purely mathematical standpoint, a color progression that transitions from light purple to dark yellow should feel roughly similar to a transition from light yellow to dark purple. But as we can see, the former feels natural, and the latter not so much.

PDF UA and WCAG 2.0 Mapping

any organizations are tasked with implementing accessibility in their electronic content and related applications through adoption of the W3C’s Web Content Accessibility Guidelines 2.0 (WCAG 2.0). WCAG 2.0, however, was written with Web content in mind and to be technically neutral in its prescriptions for Web technology. The application of WCAG 2.0 to other electronic content technologies, especially technologies that are not essentially of the Web, requires interpretation to determine how to apply WCAG 2.0 Principles, Guidelines and Success Criteria.

There are instances in which a 1:1 mapping does not exist, and in many cases, such as in PDF, it is generally appropriate to consult the accessibility standard (if any) developed specifically for that technology. – See more at: http://ift.tt/1ofuMEU

Smart Signage Aimed at All Four Tendencies–Brilliant and Fun!

In a nutshell, it distinguishes how people tend to respond to expectations: outer expectations (a deadline, a “request” from a sweetheart) and inner expectations (write a novel in your free time, keep a New Year’s resolution).
Upholders respond readily to outer and inner expectations (I’m an Upholder, 100%)
Questioners question all expectations; they’ll meet an expectation if they think it makes sense–essentially, they make all expectations into inner expectations
Obligers meet outer expectations, but struggle to meet expectations they impose on themselves
Rebels resist all expectations, outer and inner alike

Disabilities lawyer pioneers legislation for digital accessibility | The Times of Israel

“If the digital world is not made accessible, then you deny the opportunity to people with disabilities – not just deaf-blind people, but people who can’t use their hands – to participate in the social, educational and political life of our nation.”

The next big frontier is making sure that voters with disabilities aren’t disenfranchised as more parts of the voting process go digital. Goldstein is currently involved in a suit against the Ohio secretary of state alleging that certain online voting information and forms are not accessible to the blind.

[It is] very important for the disability community to privately and independently vote absentee.

Why accessibility is key for search and visibility | Search Engine Watch

Images, audio and video should all have text alternatives available in the form of alt text descriptions, closed captions and transcripts. This makes the content accessible to users with visual or hearing impairments. It also provides more information to search engines, which rely on text to find out about a site.

In a past piece on the SEO benefits of web accessibility, Mark Jackson explained that text browsers, which ignore graphic content, are often used to review how a website appears to a search engine. A website will appear in the same way to users of a screen reader, which can interpret the web for those who are blind, visually impaired, illiterate or learning disabled. In other words, making the text-based ‘version’ of your website as comprehensive as possible has benefits for both accessibility and search.
