🌙 Looking for a lightweight alternative to Redshift, f.lux, or Gammy?
Try bluelightfilter.sh – a minimal Bash script that adjusts your screen’s warmth using xrandr, without running a background service or depending on any desktop environment.
🌀 Features:
🔄 Time-based color temperature (based on sunrise/sunset)
☁️ Weather-aware adjustments (warmer gamma on cloudy days)
🎮 Fullscreen detection (disables filter during games/videos for true colors)
⚡ No daemons, no GUI — just a smart, scriptable solution for X11 users
✅ Works on any Linux distro with xrandr
📦 Dependencies: curl, jq, xrandr, and optionally xdotool, wmctrl, or xwininfo
