@Gargron lower temps are warmer/yellower, higher temps are brighter/bluer.

most commonly, 2700k "soft white" is used in most living spaces (living rooms, bedrooms, etc), 5000k "daylight" is used in work settings (offices, kitchens, around bathroom vanity mirrors, etc).

based on what you said you probably want something warmer/softer since you said "cozyness", so that'd be whatever is closest to 2700k (probably that 2600k?)
