Mine depends on area and task (mix of task lighting, accent/decor light and ambient/general light)

General for living & bedroom: 3500k or 3000k (warm light that looks cozy and comforting without being too harsh)

General for bathroom & kitchen: 4000k (bright light that lets me see things clearly but not so cold that it's too clinical)

General for study/home office & laundry yard: 6500k (coldest temp in the house, allows brightest contrast and promotes alertness, but this kind of brightness will disrupt sleep patterns so better not spend too many late study/work sessions).

Accent/decor lights (only in bedroom and living): 1000k to 2500k (still on warm spectrum so won't clash if turned on with the warm general lights on as well, gives a soft intimate glow if used without general lights).

Task lighting in kitchen: 4500k (specific for under overhead-cabinet lights to see countertop/hob while doing kitchen things)
