commit d9f57d21417b53ef91e922a63204d950010d0251
Author: jiahuiguo <jiahuiguo@google.com>

Replace hard-coded colors from ui::NativeTheme for consistency
and accessibility, and refactor to let views, not controllers
in control of presentation details, while the controller returns
a color id instead of a color.
