Many colours of noise

I like the comment about orange noise:

Since all in-tune musical notes are eliminated, the remaining spectrum could be said to consist of sour, citrus, or "orange" notes. "Orange noise is most easily generated by a roomful of primary school students equipped with plastic soprano recorders."
 

ooo, my Cwejman S1 can make the red noise.
 

Cool!

I like the idea of 'Black Noise'... that should be a genre if it isn't already...
 

If you look at that photo very carefully, concentrate, and let your eyes slowly relax, you'll suddenly see a 3D rendering of a Minimoog!! Only 35% of the population can see it.
 

Shameless Fratboy! Alternative acoustic music! Aaaaaaaaaaaaaaahhhhhhhhhhhhhhhhhh!
Whyyyyyyy????????
 

There was a canadian band called FM who put out a great album called Black Noise in the 70's.

I prefer to always call the "Brownian noise" this way, and never "brown noise"... Unless it's "Brown noise" with a capital, in reference to mr. Brown, who unfortunately had the name of a colour.

It's quite easy to create Brownian noise, and to have white noise over certain frequency ranges, but 1/f, or "pink" noise is a bit more complicated. (it would be funny if someone named Pink ever studied 1/f noise...) It only arises in some special circumstances!...

There is a great Martin Gardner article in SciAm about pink noise that everybody should read. Here is a nice page about the subject:

And one interesting characteristic about true, perfect Brownian noise is that it always hits the dynamical range of your system sometime.
