Richard,

Good questions, I had the same ones when I created my own 
Verilog parser.

The colors are not at all related to the parser.
You have to hook into snavigator/hyper/highlight.c and create
your own flex .l  file to specify what keywords to highlight.
I used ch_high.l as a template.

You also have to find and edit sninit.tcl to turn it on, this was the trick
for me to get it working.

Create a file with the list of files you want to parse and feed this
to your parser. My verilog parser is named snvp so I run

% snvp -y files.f -p /bin/more

Now I can see what goes into the database and I can also debug
easier using gdb
