Colour temperature rarely gets much thought until a room feels wrong for reasons that are hard to name. Often, the culprit is light that's too cool for the space it's in.
Warm light, somewhere in the amber range rather than stark white, tends to soften edges and put people at ease. It's the tone of candlelight and early evening sun, and most of us associate it with rest rather than task.
This matters most in spaces meant for slowing down. A living room, a bedroom, a reading corner. Cooler light has its place in a kitchen or a workspace, where clarity matters more than comfort.
Getting this right is less about the fixture and more about the bulb inside it. The right shade can look plain at midday and become something else entirely once evening sets in.
