[OS X TeX] How to find coloured pages automatically?

This should be doable, but probably not from the the TeX file.
Here's what I would try; there are probably better ways. I doubt that
there is a prepackaged solution, but would be interested to hear if
there is. My method requires some programming if you want to automate
First, I would work with a PS file, not a PDF file. Assuming you're
using TeXShop, you can set
the preferences to use dvips and tell TeXShop to keep the PS file.
The simplest thing would be just to double-click on the PS file, let
Preview open it, and figure out which pages have color. If you want to
automate this step, you could do the following: Look through the PS
file in a text editor for the color commands. These will be things like
"setrgbcolor". (You could search for just "color", I think.) Page
numbers will be identified by lines like: %%Page: 10 10. You could then
write a perl or shell or awk script to figure out which pages contain
the color figures. This is left as an exercise for the reader :-).
Once you know which pages have the color figures, there is a UNIX
utility called "psselect" that allows you to print certain pages of a
PS file. It should be installed on your system if you installed TeX via
i-Installer. You can open up a terminal window and type "which
psselect" to see if you have it and "man psselect" to see how to use
