Pick a look and the whole window follows. Every theme ships in light and dark. If none of them is right, download the closest one, change the colours, upload it back, and it sits in the gallery next to the shipped ones.

Cards in Settings › Appearance, a swatch each for light and dark, live preview.
Light, Dark, or follow the desktop and change when it does.
Download any theme as a small zip, edit it, upload it back. Up to twenty of your own at a time.

Download File Manager, then pick the bundle that grants it.
