I used Audacity to generate a pink noise sample. I used Ardour for the rest of the tests because of the useful Robin Gareus 1/3 octave spectrum analyser. Here's what pink noise looks like in the 1/3 octave spectrum analyser:
Arcade Fire, 10 out of 10 on the loudness meter. Here's the octave analysis:
This is a portion near the end of the tune. It's the closest section I could find on the track Modern Man to a true pink noise spectrum.
Here's Back to Black, Amy Winehouse:

But how about the guitarists? I was surprised to see some early Kottke blasting across the spectrum. Here's a bit of the slide guitar piece "Coolidge Rising" on Leo Kottke's Armodilla Album 6 and 12 string shown here,...very bright.

Later Kottke from "Try and Stop Me" looks much more like a nautural guitar sound.Leo Kottke, Try and Stop Me
|Chris Proctor, Henry's Shuffle|
Chris Proctor gets a full, fat sound out of his guitars. Here's the spectrum of a bit of Henry's Shuffle. Even with the full sound, the spectrum curve seems like a range of frequencies that look normal, like I would get just recording my 12-strings at home.

A surprisingly normal acoustic spectrum from Preston Reed's most jangly piece on Metal:

Kaki King has a nice full fat sound. Definitely added some overtones to this mix:
