What is the Kelvin color temperature of magenta light?

Question

and while we're at it what is the CT for absolute green? Currently I am under the impression that Green and magenta do not appear in the black body radiation scale because it never glows those colors - i'm just lost in this middle area... can anyone help?

Answer 1

You're correct; neither green nor magenta are radiated by a black body at any temperature. Magenta is blue plus red. These are at opposite ends of the visible spectrum, so you'll never get a radiation curve that includes these two colours but not those in between. In the case of green, well, the first colour you'll see when you heat a black body is red, at about 526C. As the temperature increases the maximum shifts to orange then yellow. When the temperature increases still further you don't get green, because there's too much red emitted, so instead you get white, consisting of a mix of all visible wavelengths. Finally at very high temperatures, the predominant wavelength is blue.

Answer 2

Not all stars give off black body radiation perfectly with all the colors of the spectrum.
The Sun 's temperature energy falls between 5000 degree and 6000 degrees. The color of the radiation leans toward the green at that temperature.
