Скачать или смотреть What Color Are The Stars And How Hot Are They?

In this video I teach about the color of the stars and how you can predict the temperature of stars quite accurately based on their color. The formula that I use in the video for converting RGB color values to temperature is from this paper found in this stack exchange link:
http://dsp.stackexchange.com/question...

I actually had to correct this formula slightly by applying Temp=400*CCT+5220 to it. Then it worked great! RGB values are actually quite difficult to predict temperatures from because there are only certain wavelengths that are produced by black body radiation. For example there is no green in the black body radiation color scale.
