How I found it

Nested session, Displays > Night light on (3500K). Dragged the Warmth slider near its right end; hyprctl hyprsunset temperature read 6100.

Confidence

High. Reproduced.

Explanation

The slider maps left to right as 2000K to 6500K (Kelvin ascending), but it is labelled Warmth. Higher Kelvin is cooler/bluer, so moving toward "more warmth" reduces warmth. Expected: invert the mapping (right = warmer = lower K), or relabel and show a cool-to-warm gradient track with the K value as a secondary label.
