Apple is marketing the iPhone 6 as a more high-end phone. As a result, Apple is offering three color choices for its iPhone 6 and iPhone 6 Plus phones: silver and gold, silver and white, and space gray and black.
Color is one of the most visually distinctive and personal things about a new iPhone, and Apple knows it is one of the most important choices a customer makes when buying. Originally, there was only one color for iPhone: aluminum and black. Then, Apple eventually went to two color choices: black and white. The iPhone 6 now offers customers three color choices, giving them more style options.
There was a rumor that Apple actually had to delay the launch of the white iPhone 4 to improve the UV protection and prevent discoloration. There was a strong fear that the white color would eventually wear off the phone completely or lose its brightness. Apple considered this as the phone was designed and manufactured the phone. However, the white iPhone 4 has been on the market for awhile now and has had no widespread discoloration problems. The white iPhone is still one of the more popular color choices with the older models.
