Doug, these are called 'black body radiation spectra', and as far as I know, do not depend on the material radiating. I studied this stuff when I was making knives and swords and such, and got pretty good at judging temperature by color. If I remember, dull red is about 900°, full red is about 1100°, red-orange is about 1200-1300°, and your golden orange is up at about 1400-1500°; these all in fahrenheit.

Keep your lovely devices in the orange range, and you ain't gonna be a sad hippie.

Yer pal,

P.
