A list of standardized illuminants, their CIE chromaticity coordinates (x,y) of a perfectly reflecting (or transmitting) diffuser, and their correlated color temperatures (CCTs) are given below.
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 ...

[3] [4] [5] In practice, light sources that approximate Planckian radiators, such as certain fluorescent or high-intensity discharge lamps, are assessed based on their CCT, which is the temperature of a Planckian radiator whose color most closely resembles that of the light source. For light sources that do not follow the Planckian distribution ...
The psychology of warm colors concerns the impact of certain hues on human emotions and perceptions. Warm colors, such as reds, oranges, and yellows, are known [weasel words] to create a sense of warmth and comfort, and can even provide the illusion of heat. These colors have a tendency to advance toward the eye, making them particularly ...
