Hi Brett,
Styling is normally not saved in the shapefile itself. You would create
rules based on the attribute data of your data set. There are simpler
rules (e.g. categorization based on a single attribute) and more complex
rules involving several attributes and more complex logic.
In your case you would define an attribute at your four lines that
represents the values you want to base your color scheme on and then use
one of the above.
This is really basic GIS stuff and you can find this in the QGIS
manual:
http://docs.qgis.org/html/en/docs/user_manual/working_with_vector/vector_properties.html
It is a basic GIS principle that you store properties of GIS features
and not how they are represented. Representations are built from rules.
You can then clearly separate the content (geometry and other
properties) from how it is represented and you can do several
representations out of the same data.
Hope this helps.
Good luck,
Andreas
