The color temperature of daylight varies according to the time of day, weather conditions, and direction. Midday daylight is normally taken to be 5600K, a cloudy sky will be 6000-7500K, and north light (light from the blue sky from the north rather than direct sunshine) can have a color temperature of around 10,0000K. At sunrise/sunset it could be about 2000K, and during photographers’ “golden hour” it is a little cooler at around 3500K.
