An ohmmeter is the easy way.  Make a table of 6 rows and 6 columns. 
Each row and column represents a colored wire.  Take resistance
readings between each combination of wire pairs.  Some readings will
be open.  Other readings will show a resistance.  The three wires
sharing a reading are a pair of windings.  One wire will be a center
tap.  Lets suppose two of the readings are about 100 ohms and the
third reading is 200 ohms.  The two wires with the 200 ohm readings
are the end taps, and the other color shared by the 100 ohm readings
is the center tap.
