#21 Custom Themes

Make PenPage yours. Create custom color themes, assign them to workspaces, and sync across devices.

Open the Theme Editor

  1. Tap the gear icon to open Settings
  2. Find the Theme dropdown
  3. Select "+ New Theme" at the bottom of the list
  4. The Theme Editor opens

The 8 seed colors

Every theme is built from 8 base colors. Pick the ones you like — PenPage derives the rest automatically.

Color Controls
Base Editor background
Surface Toolbar / navigation bar
Sidebar Folder & page list background
Text Primary text color
Accent Highlights & headings
Selected Selected item background
Code Code block & Markdown background
Border Borders & dividers

A live preview updates as you adjust each color — what you see is what you get.

Save & manage

  • Tap Save to store your theme (up to 10 custom themes)
  • To edit an existing custom theme, select it in the dropdown and tap the edit button
  • To delete a custom theme, open it in the editor and tap Delete

Per-workspace themes

Each workspace can have its own theme:

  1. Switch to the workspace you want to customize
  2. Open Settings → Theme dropdown
  3. Pick any built-in or custom theme
  4. That workspace now uses its own look

Switch between workspaces and each one shows its assigned theme.

Sync across devices

Custom themes sync automatically via Google Drive (stored in a separate themes.json file). Sign in with the same Google account on another device — your custom themes appear there too.

Built-in themes

PenPage includes several built-in themes (Light, Dark, and more). These are always available and can't be deleted. Custom themes sit alongside them in the dropdown.
