Brain Theme

Overview

In TheBrain, the Brain Theme (managed via the Theme Editor) controls the overall visual look and feel of your Brain. It defines how the plex, content/note area, backgrounds, fonts, and colors appear so that your knowledge environment is both readable and visually consistent across desktop, mobile, and web.

A Brain Theme is essentially your visual configuration profile: once customized and saved, it shapes how thoughts, links, and panels are presented everywhere you open that Brain.

How to Use

Trigger / shortcut:

• (Document the exact keyboard command or menu path here once confirmed for v.15.)

Context where it applies:

• Applies to the entire Brain’s visual environment, not just a single thought.
• Affects the plex background, thought/link appearance, and content area styling.
• The saved theme is synced with your account so that the same look appears on supported devices (desktop / mobile / web).

Details

Core Customization Elements

• Plex Background
  • Set a solid color, gradient, or custom wallpaper/image for the main visual map background.
  • Useful for contrast (e.g., darker background for eye comfort, lighter for printing/screen capture).

• Color Palettes
  • Control colors for thought text, link lines, and background panels.
  • Adaptive coloring can adjust system UI elements to complement your chosen palette.

• Plex and Content Styling
  • Adjusts appearance of plex elements such as link lines, gates, and chevrons (especially in mind map / tree views).
  • Influences how the content/background panels around notes and sidebars are rendered visually.

Real-Time Previews & Syncing

• Real-Time Preview
  • Theme changes can be previewed as you tweak colors, backgrounds, and fonts.
  • Lets you evaluate readability and contrast before committing.

• Cross-Device Consistency
  • Once you save a Brain Theme, it is associated with the Brain/account.
  • The same theme configuration is applied when you open that Brain on supported platforms.

Structural / Layout-Adjacent Controls

• Light vs. Dark Modes
  • Choose or design light and dark-style themes (e.g., high-contrast dark modes like a "Nocturne"-style theme).
  • Important for visual comfort and accessibility (glare reduction, night use, etc.).

• Interaction with Layout / Splits
  • Although themes don’t directly move panes, they work in tandem with layout choices (split views, full-note view, classic plex focus).
  • Font readability, table contrast, and background tone carry over whether you’re in a split-screen layout, full note, or the main visual map.

Notes & Tips

• Use high contrast between thought text and background to maintain readability, especially in dense plex areas.
• For dark themes, verify that markdown tables, code blocks, and links remain legible.
• Consider creating a small set of standard themes (e.g., "Day", "Night", "Presentation") and switching between them instead of constantly tweaking a single one.
• When documentation for TheBrain 15 becomes available, update this note with:
  • Exact keyboard shortcut(s) to open the Theme Editor.
  • Any v.15-specific theme features (additional palettes, per-view options, etc.).
