Created attachment 181268 [details] Preview Zone colors While choosing potentially problematic color pairs such as red/green, it'd be a good idea to take care of not using colors with similar luminosity values. Just giving one of the colors a lighter/more saturated shade will improve readability a lot, for that kind of users. Attached, is an image showing currently used vs. improved color pairs, for Preview Zones in the Timeline. (I'm afraid I didn't do a full survey of other possible places in the UI where this same principles could be applicable, but you could get the idea from this case) Thanks for listening!
All major OS seem to offer some kind of filters for colorblind users. Found this ticket here for KDE but also mentions links to other OS implementations https://bugs.kde.org/show_bug.cgi?id=474470 Wouldn't this work?
Yes, I know these filters exist, and they do separate the luminance of the problematic colors. The problem with those OS level filters is that they affect the whole screen (including the Monitors where video is being shown), which is often not what a color blind user would prefer. They are accustomed to see the world in that way, and imposing a filter on the reference image too, offsets their usual "point of reference", so they would be less competent to know if what they are seeing in the monitors is "right" or not.
Got it, thanks.
Thank you. From an usability point of view, only places where a pair of problematic colors are used to indicate alternate statuses should be treated with special care. So it'd require a very limited change, I think.
