Query: How can I test the Color-Correction Suitability of online content? [repost: Clarified Subject]

  • Hello,

    I'm a satisfied user of f.lux, but this is really a question about color filtering in general -- and I'm guessing this is a forum where such knowledge is fairly common.

    If I am creating content (eg. PowerPoint slides, or a Website) and I would like to confirm that it will be viewable by persons who suffer from unusual color vision (i.e. color blindness, in its various forms) -- If I create the content and then cycle through the various color filter options in the Windows 10 'Ease of Use' or 'Accessability' settings, and the content is clearly viewable under all conditions am I 'good to go'? Or doing I need to somehow do something like the 'inverse' of the Accessability settings?

  • I think these filters are intended to help actual colorblind people distinguish colors, so they aren't as good for developers to use.

    Here are a few ideas:

    1. Polypane has a bunch of accessibility options: https://polypane.app/
    2. Chrome/Edge seem to have added some of them too: https://developer.chrome.com/blog/new-in-devtools-83/
    3. Look for the actual accessibility standards - if you get enough luminance contrast in your design, you'll need to worry less about color: https://webaim.org/resources/contrastchecker/

  • Thanks, herf,

    Your reply somewhat supports what I was suspecting -- that what I actually need might be more like the 'Inverse' of the Ease of Use and Accessibility filters.

    I will go and look at the resources that you've pointed to.
