Color temperature
"Visible light" is commonly described by its color temperature. A traditional incandescent light source's color temperature is determined by comparing its hue with a theoretical, heated black-body radiator.
Color Temperature
For a star seen from sea level 45° above the horizon,
for dry air and .
Color Temperature
A stellar temperature determined by comparison of the spectral distribution of the star's radiation with that of a blackbody.

[edit] Color temperature
The kelvin is often used in the measure of the color temperature of light sources.

GThis false-color temperature map shows solar active region AR10923, observed close to centre of the Sun's disc. Blue regions indicate plasma near 10 million degrees Kelvin. Image: Reale, et al. (2009) ...
color temperature (NASA SP-7, 1965) 1. An estimate of the temperature of an incandescent body, determined by observing the wavelength at which it is emitting with peak intensity (its color) and using that wavelength in Wien law.
White balance - on digital cameras, electronic compensation for the color temperature associated with a given set of lighting conditions, ...
The ratio of blue to green to red light indicates an object's "color temperature." A 100-Watt tungsten bulb has a color temperature of about 2900 degrees (much cooler than the Sun's color temperature of 6100 degrees).
The basic approach here is straightforward enough, assessing whether the dust emission or color temperature correlates more strongly with one stellar population or another while being sure that the resulting scheme satisfies conservation of energy, ...
An unresolved infrared point source (color temperature about 600 K) in the Orion Nebula. It is the brightest infrared object known at . Discovered in 1966. (also known as the BN Object ) [H76]

depends on the wavelength at which we observe it; thus, brightness measurements are made using standard color filters (U, B, and V). Star color magnitudes are measured through these filters can be used to determine the star's color temperature.
