I am in my final year of hairdressing, and I have just done one of my friends hair at home. I used a Wella product she wanted a gold blonde and highlights. Of course the gold blond did not come out to light it was more like a 7/8, but the problem is she said the colour is very light. What colour do I need to use to tone it down? Would hazel blonde make it green?

Oh dear! My advice is not to colour friends hair at home but in future invite them into the salon or college for the training days/nights so that you have experienced people around you. I am afraid we do not use Wella in the salon so I would suggest you call the Wella helpline and have a chat with one of the technicians for advice.
