[Out vile jelly!]
Wow, this discussion is truly amazing!
Let's see if we can clear up a few things here.
1) Black body theory says that black objects absorb AND radiate heat better
than more reflective ones.
2) A pot is going to get hot mainly through conductance of heat. A silver pot
will radiate less of that heat than a black one will.
3) A totally black object will stand out like a wad of peppercorns in your
vanilla ice cream. The contrast between reflective surrounding and
something that reflects no light will be considerable (unless you kook
in deep space :~).
4) The black element on a stove glows red when it's hot, it doesn't glow black.
The wavelength of the radiation emitted by an object is a function of its
temperature, not of the object's colour.
I still can't believe the ignorance prevailing in [net] journalism today!
For someone to draw the conclusion that an object of colour x can only radiate
light of colour x is incredulous! This person should have at least have
consulted a basic physics test.
