Are you trying to order a stock piece in a set colour?
Because your hair is a load of different colours in different places.
Its quite dark at the root then becomes a dark blonde/brown and has streaks of sun lightened hair thats quite red/
strawberry blonde.
You'll need to match the colour to the area you're adding the hair too.
If you sent in a sample of hair, they should mix the colours exactly to the same proportions your own hair is.

To match the hair colour at the front of your head, it looks more like a #7 with some bleached/lightened streaks to me.
