iOS 27 refines Liquid Glass, and adds a transparency slider
A year after introducing Liquid Glass, Apple focused on readability: more even refraction, better contrast, sharper icons and user control over transparency.
At WWDC on 8 June 2026, Apple presented iOS 27 with a set of refinements to Liquid Glass, the translucent design language it introduced in 2025. SiliconANGLE described the update as a pass on readability and control rather than a redesign.
What changed
Refraction is more uniform, contrast is improved and icons are sharper. Apple also added a slider that lets people choose how glassy the interface looks, from very clear to fully tinted, and said it tuned responsiveness based on feedback.
The UX lesson
Translucent, layered interfaces look striking in a keynote but can hurt legibility in daily use. Giving users a control, and improving default contrast, is a reminder that expressive styling has to stay adjustable. The same thinking applies on the web: test text over images and blurred backgrounds, and respect settings such as reduced transparency and increased contrast.
