The higher the color temperature, the bluer and cooler the color looks, while the lower the color temperature, the yellower and warmer it looks. For example, the color temperature of an incandescent lamp is about 2700K, while the color temperature of a fluorescent lamp is about 5000K, and the color temperature of a blue sky is about 6500K.
