2700K or 3000K? How to choose the right light colour for your home
You've finally found the perfect light fixture. The design is exactly what you were looking for, the size is right… and then comes the question that many people hesitate over: 2700K or 3000K?
It may seem like a small detail, but the colour temperature has a huge impact on how a room feels. Warm and cosy? Or slightly fresher and more functional?
Let's keep it simple.
What does Kelvin mean?
The colour of light is expressed in Kelvin (K).
The lower the number, the warmer the light.
- 2700K = warm white
- 3000K = warm white with a slightly fresher appearance
- 4000K = neutral white
For residential projects, we generally work with 2700K or 3000K.
2700K: the favourite for homes
2700K is by far the most popular choice for residential interiors.
It creates a warm, welcoming atmosphere and beautifully enhances natural materials such as wood, stone and fabrics. The result is a calm, relaxing environment you'll enjoy spending time in.
That's why we often recommend 2700K for:
- Living rooms
- Dining rooms
- Kitchens
- Bedrooms
- Dressing rooms
If you're unsure, 2700K is almost always the safest choice.
3000K: a slightly fresher look
3000K produces a slightly whiter light. The difference is subtle but noticeable.
This colour temperature is often chosen for areas where visibility is more important, such as:
- Utility rooms
- Laundry rooms
- Technical rooms
- Garages
- Medical practices or workspaces
Some modern bathrooms are also designed with 3000K lighting.
Keep the same light colour throughout connected spaces
One of the most important recommendations we give is to use the same colour temperature throughout connected living areas.
Think of an open-plan kitchen, dining room and living room. Mixing different light colours in these spaces often creates visible colour differences, making the interior feel less harmonious.
For this reason, we recommend using one consistent light colour throughout your main living spaces.
Only functional areas such as a utility room, technical room or garage may benefit from a cooler light colour such as 3000K or even 4000K.
Looking for even more atmosphere?
Besides standard colour temperatures, there are also lighting technologies that allow you to create an even more dynamic atmosphere.
Two popular options are:
- Dim to Warm – the more you dim the light, the warmer it becomes.
- Tunable White – allows you to adjust the colour temperature from warm to cool whenever you want.
Both technologies deserve a more detailed explanation, which is why we've dedicated separate articles to them.

Our advice
Choosing the right colour temperature is just as important as choosing the right light fixture.
Even the most beautiful luminaire won't achieve the desired result if the light colour doesn't suit the space.
That's why, when designing a lighting plan, we don't just focus on the fixtures themselves. We carefully select the most suitable colour temperature to complement both your interior and the way you use each space.
