You can’t buy the Sony Xperia XZ2 Premium yet, but already we’re seeing evidence that a third color might be launched for the phone, with Chrome Gold possibly being offered alongside the confirmed Chrome Black and Chrome Silver shades.

That theory is based on a photo, obtained by Dealntech, which appears to show the Sony Xperia XZ2 Premium in a gold color, so as evidence goes it’s fairly compelling.
