We are currently researching perceptual contrast for assessing legibility and accessibility on graphically rich web pages and computer displays. Below are links to some of the early live experimental pages, evaluating the issue(s) in detail.
We developed this web app to simulate how someone with Color Vision Deficiency** sees the world. We accurately simulate Protanopia, Deuteranopia, and Tritanopia using the Brettel '99 &'97 models. We also present some experimental models, such as Blue Cone Monochromacity. www.myndex.com/CVD/
While the Brettel model is accurate for how certain types of CVD perceive the world, we also created an experimental model of how CVD specifically perceives sRGB monitors. Because tristimulus monitors only display three specific colors in various combinations, most of the colors that you see are metameric and non-spectral. So we also developed this sRGB CVD Simulator to simulate how someone with protanopia, deuteranopia, or tritanopia specifically sees sRGB monitors. www.myndex.com/CVD/sRGBCVD
COMING SOON: a public study that you can be involved in! Currently under development, it will evaluate how people perceive content in real world situations. Stay-tuned here as we prepare to launch that project. Presently delayed due to COVID-19.
These experiments relate to WCAG open issue number 695 and others on GitHub.#695 some pre-prints also on ResearchGate. For questions contact user Myndex on Github. (aka Color Science Researcher: Andrew Somers).

These SAPC-6 studies are close to the v7 trials. Also, the CE14 size, weight, antialias studies are useful demonstrations regarding spatial frequency.
These earlier experiments are set to offline to keep them from being crawled by bots in the interest of preventing confusion. Links availble on request.
