Answer 1

As noted in Android 5.0 Behavior Changes of the Android Developers site under Notifications:

Notifications are drawn with dark text atop white (or very light) backgrounds to match the new material design widgets. Make sure that all your notifications look right with the new color scheme. If your notifications look wrong, fix them:

Use setColor() to set an accent color in a circle behind your icon image. Update or remove assets that involve color. The system ignores all non-alpha channels in action icons and in the main notification icon. You should assume that these icons will be alpha-only. The system draws notification icons in white and action icons in dark gray.
