Ok, so you have a dynamic (often generated) csv file, and after 
generating you want to fire up QGIS and show it in a predefined way.

Then I would do:
- create a new project in QGIS
- load your csv via the csv plugin (as you did)
- style it in a way (with as much classes as you find in future)
- save the project(!) as 'mycsvproject' (File/Save Project)

Now every time you fire QGIS up and load your mycsvproject it will load 
it's data from the (fresh?) csv and show it in the way you defined in 
your project already. So newly added point will just show up in your 
predefined colors.

What Mischa proposes is a way to save te 'styling' (colors, sizes, 
classes en classication type) in a so called style file (.qml).
This is handy if you want to create a new project (every time) but do 
nowt want to define your classes and colors every time.
