Google unintentionally revealed details about its upcoming design language update—Material 3 Expressive—in a blog post that was later removed, likely posted ahead of schedule. The post, which was unearthed through the Wayback Machine (via 9to5Mac), showcases a glimpse of what Google says is a “bold new direction for design” with official details expected at Google I/O 2025 later this month.

Google’s Material 3 Expressive Leaks Early with Bold UI Changes, Faster Navigation, and Inclusive Design
Material 3 Expressive (M3 Expressive) is an evolution of Material Design reasoning, more about color, shape, size, motion, and grouping of elements to increase usability. The goal is to increase awareness of interactive sections and give the UI a more animated, contemporary look. One of the most notable of them is a floating pill-shaped toolbar, which shows a bit of the background and makes the UI look nicer and less static.
The original blog post did not contain any visuals, but leaks reveal the new language will bring interface elements that emphasize clarity and emotional resonance. Google worked with designers to experiment with screen layouts for emotions such as Playful, Energetic, Friendly, and Creative — attributes that were introduced at last year’s I/O — through these tests, it was able to fine-tune the UI for a more engaging user experience.
The company says feedback has generally been positive, and that an eye-tracking study found participants could recognize essential on-screen actions up to four times faster than with the Material 3 interface. Features such as a “Send” button which was bigger and a contrasting color to the one the rest of the keyboard was in, located on top of the keyboard, helped on this increase in speed in navigation.
Importantly, the changes in M3 Expressive helped eliminate age-related disparities in UI interaction. Users over 45 performed on par with younger users, thanks to improved contrast, larger buttons, and intuitive layouts. According to Google, apps using the new design were also perceived as 34% more modern and 32% “cooler” by younger demographics. Despite these improvements, Google acknowledges a challenge ahead: user familiarity. The company plans to gradually ease users into the new style as more apps adopt M3 Expressive throughout the coming year.
