Updated, and now Scrivener is PURPLE?!

I’m running the latest public update of Scrivener, on OSX Monterey. And suddenly, a lot of things are purple. I’ve played with the colors in the settings, but no setting seems to affect these. For example, when the Scrivener window opens, the selected items are backlit in purple. In the main Editor window, split-view mode, the selected pane header is purple. In the preferences window, checkboxes are purple, as is the selected menu item. I’ve even tried changing themes, and the purple is always there. How do I change this color?!

That’s Scrivener’s app accent color. I’m not sure if you can change that, but… in the macOS System Preferences → General → Accent color you can choose another color (this will also affect the accent color of all other programs).
