Apple has been slowly opening up iOS customization over the past few releases. Lock screen personalization arrived first. Then came home screen icon tinting in iOS 18, more flexibility in iOS 26, and a full-on overhaul in iOS 27. The iPhone is more individualistic than ever, and that is a good thing.
But there is still a gap. Android has had Material You for years, a system that pulls colors from your wallpaper and applies them across the entire OS. iOS has icon tinting on the home screen, but that is where it stops. Why not extend that to the rest of the operating system?
iOS 27 has not even reached the public yet, so maybe I am getting ahead of myself. But thematic app color schemes on top of light and dark mode feel like a logical next step.
What iOS color theming could look like
Imagine a system where your chosen icon color palette flows through the entire OS. Not just the home screen, but Settings, Messages, Mail, and third-party apps that adopt the API. Apple already has the building blocks. The icon tinting feature from last year lets you match icons to your MagSafe case color. That same logic could drive a broader theming system[reference:23].
Apple introduced color themes in Xcode at WWDC earlier this year. Developers can already choose from a range of palettes when building software. The Mac also allows a system-wide tint color for third-party apps. The technology is there. It just needs to come to iPhone.
Wallpaper-based matching would be the most natural approach, similar to how Material You works. But Apple could also offer manual color selection, letting users pick a palette that suits their taste regardless of their wallpaper.
Why Apple should do it
Customization sells. People want their devices to feel like theirs. Android has proven that with Material You, and the iPhone's lock screen customization was one of the most talked-about features in recent years. System-wide color theming would be another step in that direction.
It would also be a differentiator. Apple has always positioned the iPhone as a personal device. Allowing users to make it visually personal in a deeper way fits that narrative. And it does not have to be complicated. A simple toggle in Settings, a few palette options, and an API for developers. That is all it would take.
The case against it
Some will argue that system-wide theming adds complexity or that Apple prefers a consistent visual identity across all devices. Those are valid concerns. But Apple has already shown it is willing to add customization features that were once unthinkable. Widgets on the home screen. Always-on display. Icon tinting. The wall has been coming down for years.
Color theming is not about making iOS look like Android. It is about giving users more control over how their phone looks and feels. Apple can do it in its own way, with its own design language. The question is not whether it can happen. It is when.
