Feynmf
One of the best options for Feynman diagrams if you're using TeX or LaTeX is Feynmf, which was written by Thorsten Ohl. Check out the examples!

What do I need to run Feynmf?
A "tarball" of the package is available locally as </~furnstah/temp/feynmf/feynmf.tar.gz> but you might want to do a Google.com search to check for an updated version.

You also might want to use (or adapt) this simple csh script </~furnstah/temp/feynmf/fmf_make> for processing diagrams and popping up xdvi with the revised version. (It kills old intermediate files, to avoid confusing xdvi and dvips.) This other script </~furnstah/temp/feynmf/fmf_make2> uses Metapost instead of Metafont. You'll want to use it to make Feynman diagrams with colors.

There is a manual: </~furnstah/temp/feynmf/fmfman.ps.gz> and a three part tutorial. All of the links are to gzipped postscript files. 
  Part 1: </~furnstah/temp/feynmf/textproc1.ps.gz>
  Part 2: </~furnstah/temp/feynmf/textproc2.ps.gz>
  Part 3: </~furnstah/temp/feynmf/textproc3.ps.gz>

The manual and tutorials have many examples.

Can you show me some examples of Feynmf?

 * A simple QED vertex correction </~furnstah/temp/feynmf/qedtest.ps> and the
    LaTeX file that generated it </~furnstah/temp/feynmf/qedtest.tex> 
 * Hugenholtz diagrams </~furnstah/temp/feynmf/fig_hugenholtz.ps> and the 
    LaTeX source </~furnstah/temp/feynmf/fig_hugenholtz.tex> (you'll also 
    need hugenholtz.tex </~furnstah/temp/feynmf/hugenholtz.tex>)

How do I make Feynman diagrams using Feynmf with colors?
You'll need to run Metapost instead of Metafont to get the colors (this means that you'll need the "feynmp" rather than "feynmf" input files. Also, any colors that are not part of the figures (e.g., from external labels) won't show up until you create a postscript file (see the example). Here's an example postscript file </~furnstah/temp/feynmf/fig_rmf.ps> and the LaTeX source code </~furnstah/temp/feynmf/fig_rmf.tex>.

The instructions are given in the comments of the examples' source code: 

  * to typeset XXX.tex with Feynmp: [e.g., fig_rmf.tex]
      $ latex XXX                   [latex fig_rmf]
      $ mpost fmfXXX                [mpost fmffig_rmf]
      $ latex XXX                   [latex fig_rmf]
  * to generate a postscript file:
      $ dvips -o XXX.ps XXX.dvi     [dvips -o fig_rmf.ps fig_rmf.dvi]
  * you may need to delete the fmfXXX??? files to make sure the fonts
      are updated
