The document discusses design principles of Android KitKat 4.4, which uses a flat, gray interface to allow photos and content to stand out. By removing color from most interface elements and using it only for active elements, the interface feels simplified and user focus is on content. Shapes are used to provide clear cues for interaction. Color is then used strategically in specific contexts like popups to provide feedback to users. The simplified, content-focused design aims to improve visual communication and speed up the design process.

1. Gray is beautiful.
The future is here.
Android KitKat 4.4 Released October 2013
2. Whats the big idea?
In iOS 7 and Android, both, flat design allows photos to stand out,
and color comes to the forefront. Android takes this idea a step
further, so photos and active elements can take center stage.
The big idea: Content is king.
3. A fresh coat of paint
In Android 4.4 KitKat, all interactive elements are gray.
This accomplishes several things. Most important:
Clear communication
Color can be used more strategically to highlight
active elements. The interface falls away.

Providing color only when an object is acted on
makes for a more pleasing interaction
4. The shape of things to come
Because shapes provide clear interactive cues,
color can take a back seat until it is needed.

5. Context is everything (and nothing)
Android provides a framework for shapes to provide clear
interactive cues regardless of what else is going on in the
app visually.

7. Strategic use of color
When the interface is free of color, we can use color to provide
our users useful feedback in popups, and other scenarios
yet to be imagined.
