The themes

vvault ships Light and Dark, plus a Device mode that follows your system settings automatically.

Hover your profile picture, and the theme row (Light / Dark / Device) sits right in the menu.
Or go to Settings, section Appearance.
Device follows your system automatically. When your Mac or phone flips to dark at night, vvault flips with it.
Keyboard: press M anywhere to jump between light and dark.

In Settings, Appearance, flip on Advanced mode to customize the palette token by token (accent colors, surfaces, radii) and save your own presets.

Your public page has its own theme too: customize it from your profile so visitors see your brand, not ours.
