Before we start to talk about this, we have to make one thing clear: What is living room for?
Quoted from Wikipedia:
“In Western architecture, a living room, also called a lounge room, lounge or sitting room, is a room in a residential house or apartment for relaxing and socializing”
Let’s focus on the words relaxing & socializing, remember that is what the living room for.
Then what color temperature of light we should have to create relaxing or socializing atmosphere? Maybe we can get the answer directly from our human beings feeling to the nature. Let’s check the image below, showing the color temperature changes of daylight.
During sunrise & sunset, the color temperature of daylight is 2400K-3500K.(Yellowish White)
In the morning or afternoon, the color temperature of daylight is 4000-5000K.(Pure White)
At noon,the color temperature of daylight is 5000K-6500K.(Cool white)
Which period of the day make us feel cozy and relaxed? Let’s consider about it:
There is no doubt that during sunrise or sunset. In that period the daylight makes us feel more relaxed and cozy. That’s the magic link between nature and our human beings, we should listen to it, and follow it.
Therefore, the suggested color temperature for living rooms is 2400K-3500K, which can create good atmosphere for our relaxing & socializing.
One more tip from the lighting end-user market, in the past few years, more and more architects and designers prefer the lighting in 3000K, which can prove 3000K lighting for home requirement becomes normal for consumers.
