[sdiy] Truly red noise

A tangent to the white noise thread--

I was reading a book on electronic music awhile back and I remember coming
across some definitions for audio noise (these are off the top of my head):

white/gaussian noise - power of 1 (unity) over the spectrum
pink noise - power of 1/f over the spectrum
red noise (this is a little foggy) - power of 1/(f^2) over the spectrum

If this is correct, I should be able to get red noise by taking the negative of
the derivative of the pink noise, right?  How would this be done
electronically?

Now I've seen the "colors of noise" article here:

But there is no math given for the red noise.
