 And now, let's take a look at the new Android Chrome OS. Design is essential in today's world. So we challenged ourselves to create a design that was not just for Android phones and tablets. At its annual I.O. developer keynote, Google has released a new design language for Android, Chrome OS, and the web. Google's calling it Material Design. The new look, which was first previewed in a Google Plus update last month, includes splashes of color, refreshed iconography, and a more consistent interface hierarchy. The entire interface is based on what Google calls a quote, unifying theory of a rationalized space in a system of motion. Yeah, it's a mouthful. A video released by Google shows the new design language in action, with radically redesigned versions of Google's apps for Android and the web, including Gmail and Calendar. Google also trotted out a new look for Android's logo. It's entirely lowercase and replaces the one Google has used for the past five and a half years. Material Design represents the first real departure from the company's so-called Holo UI, first introduced with Android 4.0 in 2012. Holo came with design guidelines for app makers, which at the time helped unify the disparate styles that independent developers had used for their apps. That consistency has changed the face of Android, and although Google has only demonstrated its own Material Design app so far, it's releasing a comprehensive set of guidelines and tools for developers to create web and Android apps in line with the new style.
