Apple announced in iOS 27 a new Liquid Glass slider that lets users customize transparency levels, addressing previous complaints about readability and contrast. The feature is part of ongoing design tweaks following initial release.
Apple has introduced a new Liquid Glass transparency slider in iOS 27, allowing users to customize the opacity of Liquid Design elements. This update directly responds to user feedback and marks a significant step toward more personalized interface options.
During WWDC 2026, Apple announced that iOS 27 will feature a slider enabling users to control the transparency of Liquid Glass elements, which previously lacked customization options. The default setting will be less transparent, with the slider allowing users to increase or decrease transparency, even to the point of disabling Liquid Glass for a fully opaque interface.
In addition to the transparency adjustment, Apple is reintroducing design elements from macOS into Liquid Glass, such as improved sidebar icon contrast and uniform rounded corners across apps. Apple also plans to layer Liquid Glass effects onto app icons, adding depth even in modes like Tinted or Clear, with third-party developers able to utilize these features.
Enhanced Customization Improves User Experience
The addition of a transparency slider addresses long-standing user complaints about the readability and contrast of Liquid Glass interfaces. This change allows users to tailor the appearance to their preferences, potentially improving accessibility and overall satisfaction with the design aesthetic. It also signals Apple’s commitment to refining its Liquid Design language based on community feedback, which could influence future OS updates and developer practices.

Evolution of Liquid Design Since iOS 26
Apple introduced Liquid Design with iOS 26, emphasizing transparency and depth in interface elements. However, initial feedback indicated that the lack of customization options led to readability issues, prompting Apple to make incremental tweaks over the past year. The new slider in iOS 27 represents the latest step in refining this visual style, balancing aesthetic appeal with usability.
“The transparency slider in iOS 27 is a game-changer, giving users control over how transparent Liquid Glass elements appear, which was a major concern for many.”
— an anonymous researcher
“With iOS 27, we aim to provide a more personalized and accessible experience, allowing users to adjust Liquid Glass transparency to their liking.”
