What Liquid Glass Is and How the New Slider Changes It
Liquid Glass is Apple’s translucent interface design that makes icons, menus, toolbars, and panels look like frosted glass, blending the background with foreground elements to create depth, reflections, and subtle lighting effects across iPhone, iPad, Mac, and Apple Watch. It replaced the flatter look of earlier versions and has divided opinion because those transparent surfaces can help the interface feel lighter while also making menus harder to read, especially over complex wallpapers or content. iOS 27 introduces a dedicated Liquid Glass slider in Settings that lets you move from ultra-clear to fully tinted, so you can adjust transparency on iPhone with much more control than the earlier Clear and Tinted presets. According to Apple’s WWDC explanation, the company has also “tuned Liquid Glass so it diffuses complex content behind it much more effectively,” improving default readability before you even touch the slider.
Use iOS 27’s Liquid Glass Slider for Precise Transparency Control
With the Liquid Glass slider iOS 27 adds, you no longer have to choose between only Clear and Tinted. Open Settings, then go to Display & Brightness and tap Liquid Glass to find the new control. Move the slider toward the Clear end if you want more of the translucent, glass-like aesthetic, or toward the fully tinted side if you prefer solid, high-contrast backgrounds that improve readability. The slider behaves similarly to the transparency control Apple added to the Lock Screen clock in earlier updates, giving fine-grained control instead of a binary option. While you still cannot disable Liquid Glass completely, you can dial it back enough that tabs, buttons, and Control Center panels stand out clearly over busy wallpapers. This is the core of Liquid Glass customization in iOS 27 and should be the first place you experiment before turning to accessibility settings.
Current Workarounds: Reduce Transparency and Bright Effects
If your device has not yet received the Liquid Glass slider iOS 27 introduces, you can still adjust transparency iPhone and other devices using accessibility tools. On iPhone or iPad, go to Settings > Accessibility > Display & Text Size and enable Reduce Transparency to swap translucent panels for more opaque surfaces. On Mac, open System Settings > Accessibility > Display and switch on Reduce Transparency to make the menu bar, Dock, icons, and widgets less see-through. On Apple Watch, you can use the Watch app on your iPhone (My Watch > Accessibility) or go straight to Settings > Accessibility on the watch and toggle Reduce Transparency for clearer Notification panels and Control Center. As of iOS 26.4, there is also a reduce brightness setting under Display & Text Size called Reduce Brightness, which softens Liquid Glass lighting effects and helps if bright highlights strain your eyes.
Adjust Brightness, Motion, and Dark Mode for Extra Comfort
Beyond transparency, you can refine Liquid Glass customization by tuning brightness, motion, and appearance. Enable the reduce brightness setting on iPhone or iPad via Settings > Accessibility > Display & Text Size > Reduce Brightness to tone down glare from Liquid Glass highlights. Pair this with Dark Mode by going to Settings > Display & Brightness and selecting Dark; this hides more of the glass effect behind darker panels and often improves contrast in apps like Music and Control Center. On Mac, switch to Dark under System Settings > Appearance for a similar effect. Motion-sensitive users can also visit Settings > Accessibility > Motion and enable Reduce Motion, which now includes elements of Liquid Glass animations so transitions feel calmer. Used together, these controls let you manage transparency, brightness, and movement independently, creating a more comfortable interface without abandoning Apple’s newer visual style.
Choosing the Right Liquid Glass Setup for Each Apple Device
Because Liquid Glass cannot be fully disabled, the goal is to find a personal balance on each device you use. On iPhone and iPad, start with the Liquid Glass slider iOS 27 adds, then layer on Reduce Transparency or Reduce Brightness only if menus still feel hard to read. On Mac, combine the Accessibility > Display transparency toggle with Dark appearance to keep the menu bar, Dock, and windows legible during long work sessions. On Apple Watch, focus on Reduce Transparency so notifications and Control Center cards stand out at a glance. You can keep a clearer, more decorative look on devices where you mainly consume content, and choose stronger tinting and reduced motion where you need focus and comfort. With these tools, you can adjust transparency iPhone and across the Apple ecosystem so Liquid Glass works for you instead of against you.
