They had to make it white. You can adjust the thickness of the oxide coating on titanium to refract a wide range of colors - just not white.

The white (and the magstripe) is just a coat of something on top of the titanium.
Exactly. They could have picked any color other than white and had a nearly indestructible titanium dioxide coating.
Not for the magstripe, they couldn't.
But I haven't seen any complaints about the magstripe, just about visual blemishes.
The magstripe seems particularly prone to damage. https://i.imgur.com/Bg8yOKT.jpg
The focus of the complaints is the blemishes, which are worse on the magstripe.

Why they couldn’t cope with magstripe being a different colour to the titanium I don’t know.
