According to the leaks on X (formerly Twitter), iPhone 15 will be shipped with matching color cable!
Not only that, iPhone 15 is allegedly to get a 1.5 meter long USB-C cable, which is 0.5 meter longer than standard Android USB-C cable, but they are also braided, which enhance the visual and is said to be more durable.
Since iPhone 15 will be having matching colored cable, we can easily guess the color available on launch based on another leaked cable photo
We can assume that iPhone 15 will be available in black, white, blue, and pink based on the cable color that is being leaked.
However, everything here is still speculation and unofficial. For official news, we will have to wait for Apple Event that is rumoured to be held on September 2023.
