What Liquid Glass Is and What iOS 27 Changes
Liquid Glass is Apple’s translucent interface design that makes icons, menus, toolbars, and other elements look like they’re behind frosted glass, blending background content with foreground controls while adding lighting effects that reflect and refract across digital surfaces. It first appeared as a major redesign in iOS 26 and quickly divided opinion, because transparent menus and panels could be hard to read or even uncomfortable for some users, especially in dark mode. You cannot fully disable Liquid Glass on iPhone, iPad, Mac, or Apple Watch, but you can reduce its transparency, brightness, and motion. Apple started by offering simple Clear or Tinted styles in iOS 26.1, then added options like Reduce Transparency and Reduce Brightness. According to BGR, iOS 27 finally adds a dedicated Liquid Glass transparency slider so you can pick any level between ultra-clear and fully tinted for a more comfortable and readable interface.
Dial Back Transparency with Accessibility Controls
If you want fast relief from strong Liquid Glass transparency, start with the systemwide accessibility tools. On iPhone or iPad, go to Settings > Accessibility > Display & Text Size and enable Reduce Transparency. This swaps many translucent backgrounds for more opaque panels, improving contrast in folders, menus, and system overlays. macOS offers the same control under System Settings > Accessibility > Display, where turning on Reduce Transparency makes the menu bar, Dock, icons, and widgets more solid and easier to distinguish. On Apple Watch, you can adjust these Liquid Glass settings from the Watch app on your iPhone via My Watch > Accessibility > Reduce Transparency, or directly on the watch in Settings > Accessibility. Notification panels and Control Center are good places to compare before and after. These Reduce Transparency options are the quickest way to perform a basic transparency adjustment across Apple’s platforms.
Using iOS 27’s New Liquid Glass Slider
The headline feature for Liquid Glass settings in iOS 27 is a dedicated transparency slider. Apple places this control in Settings so you can move from “ultra-clear” to “fully tinted” and everything in between, instead of choosing only Clear or Tinted modes. This slider builds on the earlier Liquid Glass option introduced in iOS 26.1 under Settings > Display & Brightness > Liquid Glass, where you could select Clear for a more transparent look or Tinted for a more opaque, high-contrast interface. Now, the slider lets you fine-tune translucency until icons, toolbars, and menus feel comfortable in your everyday apps, including those with complex backgrounds like Music or Control Center. According to Apple’s WWDC explanation cited by BGR, the company has “tuned Liquid Glass so it diffuses complex content behind it much more effectively, while also creating more depth and separation” to improve readability for most users.
Reduce Brightness and Motion for a Calmer Interface
If Liquid Glass feels visually intense, you can tone down both brightness and animation. As of iOS 26.4, iPhone and iPad include a Reduce Brightness toggle in Settings > Accessibility > Display & Text Size. Turning this on softens some of the lighting effects that come with Liquid Glass, making highlights and reflections less glaring without changing your main brightness setting. For motion, go to Settings > Accessibility > Motion and enable Reduce Motion. Apple has expanded this option so it now tempers Liquid Glass effects as well, shrinking or simplifying animations that might otherwise feel overwhelming. These adjustments work alongside transparency and the iOS 27 slider, so you can create a calmer visual style that still keeps the modern look. If you pair these settings with darker themes or tinted panels, the interface becomes easier on the eyes during long sessions.
Match Liquid Glass to Your Home Screen and Apple Watch
To complete your iOS 27 customization, adjust how Liquid Glass interacts with your Home screen and Apple Watch. On iPhone, long-press an empty area of the Home screen, tap Edit, then Customize. There you can flip icons and widgets between light and dark using the sun icon, enlarge icons with the square icon, or choose Dark, Clear, or Tinted Home screen styles at the bottom. The Dark and Clear options can be set to Always or Auto, so they adapt between day and night, while Tinted offers sliders to change tint color and lightness, plus shortcuts to colors from your wallpaper. On Apple Watch, the Reduce Transparency option in Apple Watch settings helps notification panels and Control Center stand out from watch faces. Together, these Liquid Glass settings let you align transparency adjustment, motion, brightness, and color across iPhone, iPad, Mac, and Apple Watch for a consistent, readable setup.
