Colourful metal for the next iPhone 6?

New day and new rumors for the next model of the iPhone. The rumors says than the new iPhone can get ideas from his predecessor about the colours of his body.

The Apple company says than he will abandon the plastic body of the 5C series but not the colours. In fact, the iPhone 6 can have a coloured metal case, like the current iPod.
This series can represent an only model and will abandon the duality of the S and the C models.

You like this idea? Which colour you like?
