I would preferer not to mix data and their graphical representation 
for vectors. Required color for a vector often changes, as well as number 
of classes etc. Non of other GISes store the color with vectors, AFAIK.

There is quite easy semi-automatic way to assign 
symbology to attributes in QGIS:
