Description gaming.sx7xr 2025-05-06 04:47:58 UTC
SUMMARY
Taking a screenshot with Night Light enabled causes incorrect colors in the resulting screenshot.

STEPS TO REPRODUCE
1. Turn on Night Light. Make sure it's turned up really strong so the effect is noticeable.
2. Take a screenshot. Use Fullscreen screenshot or Rectangular region mode. (Choosing a specific window to capture does not cause the bug; the resulting screenshot in that case will look normal)
3. Turn off Night Light.

OBSERVED RESULT
The resulting screen capture has incorrect, warped colors. Red and yellowish shades look pale. It seems like Spectacle is trying to overcompensate for the color distortion that Night Light causes.

EXPECTED RESULT
I expected that the screenshot colors would look normal, as though you didn't even have Night Light on when you took them.

Hi - merging this in with the existing bug report around washed-out or pale-looking screenshots with Night Light active. Thanks!
