Well hate to break it to you but it's in essence true if you were previously unaware. Different spectrums of light have different heat properties. The kelvin scale is related to the light produced at lower or higher temperature.

Objects that are made hot will glow red. The hotter they get, the more white or even blue they will glow and thus light they emit, the blue light spectrum carries more energy per photon than red light and thus more heat. Proven fact.

Also, on the other end of the spectrum why do you think they use Infared heat lamps to heat food? It's HOTTER light. Maybe you did'nt actually read the Wikipedia links about thermodynamics and what kelvin actually is...figures lol

You care to dispute these facts with a relative argument of supporting info?

Of course not, just more posturing from the experts of nothing but drama.
