Quoting from http://android-developers.blogspot.se/2014/08/material-design-in-2014-google-io-app.html:

In material design, UI element color palettes generally consist of one primary and one accent color.

The accent color is used more subtly throughout the app, to call attention to key elements. The resulting juxtaposition of a tamer primary color and a brighter accent, gives apps a bold, colorful look without overwhelming the app’s actual content.
