A new iPhone 17 Pro feature that allows the phone to change colors is proving popular.

Turns out, the new iPhone 17 Pro’s color shift is more loved than hated.
The color shift affects a significant portion of devices, despite initial reports suggesting it was limited to a few units. The lack of photographic or video confirmation suggests the issue might be less widespread than online discussions indicate.

Judging from online responses, a sizable portion of users are not bothered by the color change. Many users appreciate the alteration of their iPhone 17 Pro's appearance.
The cause of the color change is likely unintended by Apple. It is improbable that the company intentionally designed the orange model to gradually turn pink. It is speculated to be an unintended consequence rather than a deliberate feature.
The prevailing theory suggests the Cosmic Orange model may possess a permeable anodized aluminum surface. This would make it susceptible to reactions with certain substances or oxidation over time. An imperfect protective layer could leave the aluminum vulnerable, leading to potential reactions.
Exposure to substances such as hydrogen peroxide, found in some cleaning products, or prolonged sun exposure could cause the pigment to change towards pink.

While some users find the change appealing, others may be dissatisfied. Given the phone's high cost, a color change could negatively impact its resale or trade-in value.
Online "solutions" have emerged, with some users claiming sun exposure accelerates the pink hue. However, exposing iPhones to heat could cause damage solely for a color alteration.
Other recommendations involve using cleaning products to induce or reverse the change, but this could ruin the phone's finish. A pink phone case is a safer alternative.
To prevent the color change, using a dark or opaque case can shield the phone from sunlight and other potential causes. Avoid cleaning products that contain harsh chemicals, such as hydrogen peroxide.
Although not ideal, verified cases with photo evidence remain limited. This issue may remain a minor, isolated occurrence rather than a widespread problem.
