Apple is planning to introduce a "Deep Blue" color option to replace the Space Gray color option for the upcoming iPhone 7, according to a new report from Japanese website Mac Otakara. The new color will stand alongside the already available Silver, Gold and Rose Gold.

Mac Otakara says Apple plans to discontinue the "Space Gray" color, which was introduced with the iPhone 5s in 2013. The lighter shade replaced the darker slate black used on the iPhone 5. The color has since found its way to other Apple products, like the iPad Air, iPad Pro and 12-inch MacBook.

The Cupertino company has steadily added color options to its iPhone lineup. In 2008, Apple debuted a white color option alongside the black iPhone 3G. The company later renamed the white option Silver with the iPhone 5s, which also saw the debut of the Gold color option. Most recently, Apple added the Rose Gold option with the iPhone 6s.

The report also says the iPhone 7 will keep the same LCD glass surface that current iPhone models employ. This corroborates an earlier report saying that no major display upgrades are expected until 2017, when Apple switches to OLED.

Apple is expected to announce the iPhone 7 this September, with recent rumors suggesting the new iPhone will have a design similar to that of both the iPhone 6 and 6s and more radical changes coming to the 2017 iPhone. However, the iPhone 7 may not include a 3.5mm headphone jack. Additional features for the iPhone 7 could include a faster A10 chip, waterproofing, adjusted antenna bands, faster LTE and Wi-Fi chips and more.
