ur right, but wrong.. in my mention, thats the spectral power distribution-- a representation of the radiant power emitted by a light source as a function of wavelength..

Color temperature is measured in degrees Kelvin, which indicathe hue of a specific type of light source. Higher temperatures indicate whiter, "cooler" colors, while lower temperatures indicate yellower, "warmer" colors.
