Apple is expected to launch larger iPhone models later this year, and they may arrive in a variety of colors. 9to5Mac reports that reliable analyst Ming-Chi Kuo is predicting that Apple’s rumored 6.5-inch OLED iPhone will launch in black, white, and a new gold color. The rumored 6.1-inch LED iPhone will also reportedly debut in grey, white, blue, red, and orange variants.

If the report is accurate then Apple is introducing at least four new colors for its 2018 iPhones, an unusual step for the company. Apple typically debuts a red variant some months after a new iPhone launches to promote Product (RED), an organization that campaigns to fight HIV and AIDS in Africa. Apple has never released an orange version of the iPhone before, and the company has mostly relied on cases to add color to the iPhone’s typical grey / black and white options. The iPhone 5C debuted back in 2013 in green, blue, yellow, pink, and white variants thanks to a polycarbonate back.
