Use ctrl.setOptions() to drive the map programmatically, and onViewOptionsChange to receive toolbar changes back into your app. The external controls in the sidebar stay in sync with the toolbar — change either one and both update. The programmatic action buttons demonstrate resetZoom() and highlightBin.

The colour-scheme dropdown includes teal-rose, a custom palette this page registers with registerColorScheme() before rendering — pick it here, or open the toolbar's own palette picker and see it listed there too. That is the point of registering rather than passing colours per call: a registered scheme becomes available everywhere, with no further wiring. Note this is the data palette (die colours). Theming the surrounding chrome is a separate mechanism — see the theming demo.
