Fluent Design in Windows 10 Mail and Calendar rolls out publicly

With Windows 10 Fall Creators Update, Microsoft introduced its vision for the future of user interface design. The company started to add more and more Fluent Design elements to its own first-party apps, including the Start menu, Calculator, Maps, Store, Settings and Groove Music. A new version of the Calendar and Mail apps got a refined look with Fluent Design bits in the UI.

This update was previously released to the Fast Ring insiders. The user interface of apps comes now with blur and features the reveal highlight effect. Here is how it looks.

The official change log mentions the following changes.

Mail and Calendar have a refreshing new visual design and background photo.

Choose from hundreds of new colors to brighten up your calendars.

1. Select the arrow next to the calendar you'd like to change.
2. Select More Colors.
3. Drag the slider to choose a color.

Fluent Design is Windows 10's new  UI, previously known by its code name "Project NEON". It is a new design language which is focused on simplicity and consistency along with cool animations. It also adds Windows 7’s Aero Glass-like effects to the Universal app frame and controls.

Tip: You can disable Fluent Design visual effects in Windows 10.

Key aspects of the Microsoft Fluent Design System are as follows.

Material: A graphical solution which emulates the "sensory and invigorating" feel of the materials that things around us are made of.

Motion: A set of animations which give an idea on how to interact with new UI elements like an app menu opening or drawing the user's attention to controls and flyouts which appear on the screen.

Light: Soft highlights of important buttons and features to draw the user's attention.

Depth: Transition animations which make an impression of opening the next level or layer of data presented by the app.

Personally, I like the transparency effect applied to the app. What about you? Do you like this change?
