I worked with Google at a material design sprint on some quick prototypes of incorporating material design in to Amex Mobile. The prototypes explore a range of things from the design spec, from interaction styles on buttons and cards to visual design that follows grid and spacing guidelines.
A More Material Drawer
At the design sprint, I explored a range of approaches that brought the Amex Mobile drawer more in line with Material. Bold colors, full size cards, multiple cards and color sampling (awesome!) were some of the directions I took.
