    Give Flux a try. https://justgetflux.com/ It did it before night mode and does it far better. ;). - Source: Hacker News / 8 months ago
  • Tools that keep me productive
    For those evenings where I'm in front of the computer, f.lux is a must. Like some wise person said, "Be kind to your eyeballs". macOS's Nightshift kind of works, but f.lux destroys it. - Source: dev.to / 8 months ago
  • Ultra Librarian Joins Flux to Take the Hard Out of Hardware
    Having never heard of Ultra Librarian, I thought this was somehow related to https://justgetflux.com/ and that they'd made a switch from doing color changing to hardware. - Source: Hacker News / 10 months ago
  • Is it just me who dislikes the winter update with the change of colors?
    Reshade might help with the color tones. I normally use f.lux for Windows, but I don't know how much it might help. Could be worth trying, though. Source: about 1 year ago
