The house above appears a light cream during midday, but seems to be bluish white here in the dim light before full sunrise. Note the color temperature of the sunrise in the background. Video camera operators can white-balance objects that are not white, downplaying the color of the object used for white-balancing. For instance, they can bring ...
Colors using a halophosphate formulation are usually indicated by WW for warm white, W for (neutral) white, CW for cool white, and D for the bluish daylight white. Philips and Osram use numeric color codes for tri-phosphor and multi-phosphor colors. The first digit indicates the color rendering index (CRI) of the lamp.
Good quality consumer CFLs use three or four phosphors to achieve a "white" light with a color rendering index (CRI) of about 80, where the maximum 100 represents the appearance of colors under daylight or other sources of black-body radiation such as an incandescent light bulb (depending on the correlated color temperature).
The White bulbs produce white light with a color temperature of 2700 K (warm); the White Ambiance bulbs produce white light of color temperature adjustable between 2200 K (warm soft white) and 6500 K (daylight). The White and Color Ambiance range can generate white light adjustable from 2000 K to 6500 K, and also adjustable colored light.
An incandescent bulb has a color temperature around 2800 to 3000 kelvins; daylight is around 6400 kelvins. Lower color temperature lamps have relatively more energy in the yellow and red part of the visible spectrum, while high color temperatures correspond to lamps with more of a blue-white appearance.
