Today's hot take: Peer review is not a replacement for critical thinking.

Bridge PCA is rebooted and running at bridgepca.com Bridge PCA uses the APCA contrast engine, but provides a modified output that directly indicates WCAG 2 compliance.

One of the most important things about our public education system is at risk of being destroyed. 17 states are suing the federal government to bring down Section 504, which is arguably the single-most important law that paved the course of my entire life. www.frank.computer/blog/2025/02...

Section 504 is under attack

A right that I had as a disabled student in the US is at risk of being destroyed.

Martians will be speaking at Figma’s main conference 🤯 So proud of our design team! They’ll be talking about dynamic colors—the result of our work around the OKLCH, APCA, and Apcach ecosystem.

When developers and designers are in love, they make programmable colors! Learn about this harmony from @inazarova.bsky.social and @objartel.bsky.social at @figma.com Config on May 8, live in San Francisco or virtually. Register: config.figma.com #config2025

Hello Bluesky! 😄 Just to see how this works, for my first post, here's my side project inclusivecolors.com for creating WCAG accessible color palettes for web/UI design. Feedback very welcome! #accessibility #a11y #wcag #design #graphicdesign #webdev #webdesign #uidesign #css #figma #tailwind #ux

Service skeet: @ichimnetz.com + team made a color contrast tester that evaluates against both calculation systems simultaneously: palette-tester.9elements.com BTW, I'm as much of a huge fan of APCA as I'm of OKLAB + OKLCH. All those systems that adhere to human perception make so much more sense! 👏🏻

Accessible Color Palette Tester

Create and test color palettes for WCAG & APCA contrast compliance. Name, reorder, and compare colors with real-time contrast ratings. Save & share via URL.

Say hello to Pinwheel, an amazing way to convert colors and create design systems. bjango.com/mac/pinwheel/

I built a little tool to check color contrast across an entire palette. 🎨 • Supports both WCAG 2.0 and APCA 
 • See how all colors compare at a glance • Import/Export CSS or JSON variables
 • Make sure your palette works for everyone Try it: palette-tester.9elements.com

Pinwheel does WCAG and APCA contrast testing, and so much more.

Added basic mobile support to my color palette creator and lots of little bug fixes. 😄 Please reach out if you have any feature requests or challenging problems with creating your own branded palettes! www.inclusivecolors.com #designsky #a11y #design #webdesign #css #ux #accessibility #buildinpublic

Thanks to the APCA algorithm, all colors stay visually cohesive across transformations. Under the hood, it leverages the OKLCH color model (of course), some opacity magic, and the real secret sauce: apcach, developed by Anton Lovchikov.

I am sick to death of ableist bullies that claim to be accessibility advocates. FAFO, and the “find out” is coming soon.

@mary.my.id Just to mention, APCA is part of the APCA Readability Criterion, an open standard available from Inclusive Reading Technologies, Inc. A California non-profit, dedicated to science-based standards and research to improve readability for all. www.readtech.org/ARC/

APCA Readability Criterion • Contrast

The APCA Readability Criterion (ARC) provides a range of recommendations for making visual content on illuminated displays more accessible to all users, especially with visual impairments

Now looking for volunteers for a color vision study. We are particularly interested in individuals with color vision deficiency, however all vision types are welcome, age 21 and up. If you are interested please email: cvdstudy@myndex.com #a11y #accessibility #cvd #colorblind

Honestly having a really strong understanding of your walk-away point & what you’re willing to accept or not (and sticking to it!) is so helpful. A lot of situations/people will push to see how little you’ll accept, but they can & will accommodate more. Happens in politics all the time but life too

APCA improves accessibility over WCAG2 contrast by: 1) Correctly calculating reds and oranges, helping protan color insensitivity. 2) Correctly calculating dark mode, helping literally all users. 3) Using well established peer-reviewed vision & readability science to improve actual accessibility.
