> green-screen text causes eye strain, You have any data to back that up? My favorite color scheme is green-on-black, followed by white-on-green. I find white and blue backgrounds the worst for eye strain. Low brightness with high contrast seems to be another important factor to reduce strain.

What do you suppose would motivate someone who just looked at an image to start talking about eye strain? Maybe the pain behind their eyes started them thinking about the last time they had this problem? Actual green screen phosphors are much lower saturation (and brightness) than the green on black image on that github page. That particular green would be more at home on a Hemp Festival advertisement. It's - to me - an interesting example of how terminal emulators are definitely emulators. This would be pretty close to what a brand new 'green screen' might look like, and older ones would be faded: https://cf.ydcdn.net/latest/images/computer/_OPAL1.GIF https://cf.ydcdn.net/latest/images/computer/_OPAL1.GIF A reasonable overview of saturated colors: https://uxmovement.com/content/why-you-should-avoid-bright-saturated-background-colors/ https://uxmovement.com/content/why-you-should-avoid-bright-s... Pure white on a bright (saturated) blue background is probably the worst color pairing you can get. I agree. But I'm not talking about saturated blue, or pure white. I'm talking about light (pale, if you like that word better) blue and off-white (in the ballpark of "easier on the eyes", but that's not quite right). This is Wordperfect's blue, which is a bit darker than we used (probably closer to YAST2's color scheme): https://discourse-cloud-file-uploads.s3.dualstack.us-west-2.amazonaws.com/boingboing/original/3X/6/f/6f9f09bdba548af220df7f3761d845174ddaca0d.gif https://discourse-cloud-file-uploads.s3.dualstack.us-west-2....

  FYI, that UX Movement article misrepresents the few studies that it actually cites and offers no evidence for its claim regarding saturation causing eye strain. I know this because someone complained at me recently about a design, linked to that article, and I actually bothered to read the couple of studies it did cite. Where the UX Movement article says “saturation and brightness have a more significant impact [than hue on arousal]”, one of the studies it cites clearly states that brightness had no impact on arousal. This obvious mistake calls into doubt (for me, at least) whether the author has any objective basis for their claims. On the other hand, this study which actually looks at colour preferences of people experiencing eye strain [0] appears to show (Figure 1) that people experiencing eye strain don’t select away from green, which seems to refute fairly strongly your claim that green text causes eye strain for everybody. This study references several other studies on the effects of colour overlays so it is probably a good resource for additional research.
