Yes, you can change the color. About the look - not easily except the size of the unit.
Please take a look at this example, I did the similar thing and created a new race, faction and units (the newly created Iron Golem should be in the units file for the new faction). color and size definitions:
<Color_Metal>70,80,100,255</Color_Metal>
<TacticalModelScale>1.3</TacticalModelScale>
