The Harmony UI Controls Toolkit is a software add-on that includes new red-, green-, blue-, and grey-colored additions to the LabVIEW front panel. The add-on includes these four colors to represent a harmonic balance. You can customize all control types such as gauges, charts, graphs, switches, rings, arrays, icon-based buttons, and more. The new controls and indicators from the Harmony UI Controls Toolkit appear in the LabVIEW Controls palette.
