MaterialOne is an Android 5.0 notification dropdown theme for Vex, a Control Centre tweak.

This package has two parts, the Vex theme and matching CC icons for Winterboard. You'll need to apply MaterialOne in Vex settings and MaterialOne in Winterboard for the full effect. Hopefully a future update to Vex will allow me to strip out the WB part.
