Light colour temperature plays a huge role in how a room looks and feels. Whether you're after a cosy vibe or a crisp, energising atmosphere, understanding the Kelvin (K) scale will help you make the perfect lighting choices.
What Is Colour Temperature?
Measured in Kelvins (K), colour temperature determines how "warm" or "cool" a light appears:
-
2700K–3000K: Warm white – soft, cosy, ideal for relaxing spaces
-
3500K–4100K: Neutral white – balanced, great for workspaces
-
5000K–6500K: Cool white/daylight – bright and energising, perfect for task lighting
Best Colour Temperatures by Room:
-
Living Room: 2700K–3000K for a warm, inviting atmosphere
-
Kitchen: 3000K–4000K for clarity with a touch of warmth
-
Bathroom: 4000K–5000K for accurate grooming light
-
Bedroom: 2700K for winding down in the evening
-
Home Office/Study: 4000K+ to boost concentration and reduce eye strain
Tips for Choosing:
-
Use dimmable lights to adjust brightness and mood
-
Consider smart bulbs with adjustable temperatures
-
Combine lighting layers (ambient, task, accent) for flexibility
Final Thoughts:
Getting colour temperature right is just as important as choosing the fixture itself. It influences mood, comfort, and functionality in every room.
