Apple iPhone 17 Pro and iPhone 17 Pro Max owners are reporting that the Cosmic Orange colour is fading to pink, raising quality concerns about Apple's latest premium devices. The colour change appears most prominent around the aluminium frame and camera housing, where the orange finish fades unevenly over time.Multiple users have confirmed similar fading issues across both Pro models, with frames and rear surfaces gradually changing from bright orange to light pink or rose gold hues. So far, this issue appears to primarily affect the Cosmic Orange version, though some reports mention Deep Blue units experiencing discolouration as well. The first case reportedly came from a user in Japan, where images showed that while the MagSafe ring area retained its original orange colour, the aluminium frame and surrounding rear surface had significantly faded.Users believe the fading could stem from natural oxidation of aluminium when the surface protection layer is compromised. Apple usually applies an anodised layer to prevent this reaction, but if this coating is incomplete or defective, exposed aluminium may gradually change colour due to chemical reactions.Some users claim UV exposure accelerates the color change, with devices left outside in the sun showing faster discolouration. The most noticeable discolouration occurs around the frame and camera module—areas frequently touched or exposed to friction. Reddit users documented at least 10 iPhones showing similar signs, though the degree of fading varies.Apple has yet to release an official statement, though industry insiders claim the company is aware of the issue and is reviewing internal reports. Affected users should document the color change with clear photos and contact Apple Support or visit an Apple Store for evaluation. If confirmed to be a material defect, users may be eligible for free replacement within the warranty period.
