Google has just revealed a new design language for Android, Chrome OS, and the web. The new look — which was first previewed in a Google+ app update last month — includes splashes of color, refreshed iconography, typography, and a more consistent interface hierarchy. The entire interface is based on what Google calls a "unifying theory of a rationalized space and a system of motion." 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.
