Mani of the Week: Boots No7 Siren

I have been coveting the Chanel nail polish in Dragon that Pink Bow wears and so when in Paris in October I thought it would make the perfect souvenir but alas, they were all sold out:

On my return I decided to treat myself to a nail colour from Boots No7 with my £5 voucher and so set upon this colour - Siren - which is very nearly the same shade of red.

What do you think? Can I pass it off as Chanel?
