alt Hacker NewsOne of my pet peeves about screen UIs is that they're worse than they need to be for night use. Modern dark themes are blue-heavy, which negatively impacts both pupil response and bleaching more than colors of the same luminance with more green and red.
There should be two dark modes: a simple dark mode, like most dark themes today, to work in dimmed lighting, and an actual night mode, designed to be legible but not mess with adaptation in total darkness. I don't know the research on this (and I'm sure military and aviation have lots of data here), but intuitively it should use mostly thin red and green lines.
