冷暖人间 cool light/warm light

夜深人静，隔邻住家的阳台，分别亮起白灯，（橘黄色的）暖灯，着实醒目。它们似乎通知我们世间人情世故，也会有冷暖之分。

Traditionally, most Asian families prefer to use bright @ cool light to lit up their home at night, whilst Caucasians prefer warm light.

I only started to use warm light at home when I was staying in US (because the default light bulbs were warm lights). When we moved back to Singapore, we fall back to cool lights again at home. 

Somehow, I feel that visibility is better with cool light, and the brightly lit home is not that warm under cool light.
