Legibility is not a setting
Liquid Glass shipped this year and the arguments about reading started on day one. A visual language is a promise about reading, and legibility belongs in the default, not in Settings.
Every visual language makes a promise about reading. Flat design promised that text would sit on a known background and always be legible, and it kept that promise at the cost of personality. A glass material promises depth and context: you can see what’s behind the thing you’re using. The bill for that promise is legibility, and someone has to pay it.
Apple introduced Liquid Glass on June 9 across every one of its platforms. The arguments started the same day: text over moving backgrounds, controls that change color with whatever sits behind them, contrast that depends on your wallpaper. When iOS 26 shipped in September, the complaints came from people using it every day.
Where the cost lands
Platforms pay for a material with rules: when the glass frosts, how much contrast the system guarantees and over what, and what happens when an app puts busy content behind a system control. Those rules decide whether the material works on the worst screen in the system.
The usual fix is a setting: reduce transparency, increase contrast. Those settings should exist. But a material that needs a setting to be readable has moved its cost onto the people least able to pay it, and onto everyone else on a bad day. Legibility belongs in the default.
The most useful constraint I’ve worked under is distance. On Android’s docked tablet, the screen has to read from across the room. A screen read at ten feet doesn’t get a setting. It has to work the first time.
The worst-background test
For anyone building on a glass platform: test every screen on the worst background you can find, not the one in the marketing render. Put a busy photo behind your toolbar, then a white page, then a video. If the text holds on all three, the material is earning its keep on that surface. If it doesn’t, frost it there, and don’t wait for the platform to do it for you.
The setting arrived
This week iOS 26.1 added a toggle between Clear and Tinted glass. It’s a good setting to have, and it helps the people who go looking for it. Everyone else still reads over a busy photo in bright light with whatever the default gives them. The real fix is the one nobody has to find.
