qgis - Assign multiple colors to features within a single vector layer

I want to give multiple colors to different features within a shapefile based on attribute values , is this possible in QGIS ?

If yes what is the procedure ?

Is there a way to provide color by means of hexadecimal codes ?

Answer

You can change the styles of the shape file in the layer properties. Double click the layer and select style.

Select Categorized style and choose a field you want to visualize. Remember to classify your values before leaving the dialog.
