Apple’s first foldable, the iPhone Duo, isn’t flaunting too many colours. Unlike the other iPhone 18 Pro and iPhone 18 Pro Max released alongside it, the iPhone Duo is available in only two shades.
iPhone Duo Colours
Apple ideally makes sure the iPhones are clearly identifiable by their colour alone. But that isn’t completely the case this time around. The iPhone Duo comes in two colours:
- Star White
- Night Sky
The Star White shade is a plain and simple white colourway but has that stylish iPhone touch. It doesn’t scream New iPhone! But it suits the tone of a premium foldable phone with a shiny grade 5 titanium edge that Apple says is "polished to a mirror finish".

You may be forgiven for confusing the iPhone Duo with the iPhone 18 Pro and iPhone 18 Pro Max, which come in a silver colour. But if the white isn't too obvious, the camera pill and wider form of the iPhone Duo should give a hint.

The Night Sky colourway has a deeper bluish hue that's very distinct from the Pro iPhones this year. It’s almost black with a touch of blue. It also comes with the same titanium frame, but the sides don't appear as glossy as the one on the Star White model.

Which iPhone Duo Colour Is the Best?
If you’re not sure which one to get, pick the Star White iPhone Duo. It’s hard to go wrong with the brand-new white of a new iPhone. But if you want people to know from afar that it’s truly an iPhone Duo, the Night Sky variant is the way to go!
Personally, I think Night Sky is a bold choice. There's no other colour like it. The darker Night Sky is quite deep, and in certain lighting conditions, some might mistake it for black.
