💖 xsct — X11 set screen color temperature 💖

okay bestie, gather round, because this little cutie (xsct, from the xsct(1) manual) is about to fix your eyeballs at 2am 🌙✨ it literally just sets your screen's color temperature, that's the whole vibe, and it does it flawlessly.

✨ SYNOPSIS ✨

xsct [options] [temperature] [brightness]

that's it. that's the whole girl. options, temp, brightness, slay 💅

---

🦋 DESCRIPTION 🦋

xsct sets the screen's color temperature. periodt. that's the job, she does it, she ate 💖

---

🎀 OPTIONS 🎀

• -h, --help — shows you the usage info and then dips. bye 👋
• -v, --verbose — spills the debugging tea, so you can see exactly what's going on 🔍
• -d, --delta — shifts the temperature and brightness by the temperature and brightness values you passed, instead of just straight up setting them. nudge nudge ✨
• -s, --screen N — zero-based index of the screen to use. yes bestie, zero-based, so the first one is 0, not 1, don't come for me 🙈
• -t, --toggle — flips between night temperature and day temperature. main character energy switching outfits 🌗
• -c, --crtc N — zero-based index of the CRTC to use. (also zero-based, same rules apply, we stay consistent 💅)

---

🌸 ARGUMENTS 🌸

• [temperature] — the black body temperature.
  • if the value is 0, xsct sets the color temperature to the default of 6500 — so 0 is lowkey just "give me the default pls" 🫶
  • if no arguments are passed at all, xsct estimates the current display temperature and brightness. she's perceptive like that, she reads the room 👑
• [brightness] — linear brightness between 0.0 (inclusive) and 1.0 (inclusive). and if you don't pass a parameter, the default value is 1.0 — full brightness, no notes ⭐

heads up bestie: both ends of that brightness range are inclusive, so 0.0 and 1.0 are both fair game. no guessing outside that, okay? 💀
