Choose a ThinkForge theme to change the application's colors and appearance. Switching a theme updates the whole interface immediately — there is no save step and no restart.
ThinkForge includes light and dark presets. You can also create, edit, import, and export custom themes with the Theme Editor.
Choosing a Theme
Open Settings, then Appearance. Every available theme is drawn as a card showing a background preview, an accent bar, four color swatches, and the theme name. Built-in presets appear first. A Custom Themes header and second row appear once you have at least one custom theme.
Clicking a card applies that theme immediately. The active theme's card is drawn with an accent border and a semibold name.
Open Theme Editor opens the editor for building or cloning a theme. Built-in presets are read-only and must be cloned before editing. See Creating Themes.
Light and Dark Switching
ThinkForge decides whether the application runs in Light or Dark mode from the theme's background color brightness. A light background switches the app to Light mode; a dark one switches it to Dark.
This automatic switch is what keeps tooltips, menus, context menus, and other system popups readable. Those surfaces follow the light or dark mode rather than the theme's own text color.
The result: pick a theme with a light background and the whole interface — including popups — reads as a light theme, with no separate mode setting to keep in sync.
Main-Window Tab Accents
Main-window tabs use your theme for their backgrounds and text. A thin accent line identifies the kind of surface: Project Navigator is blue, Tools is purple, documents are cyan, Project Map is green, Automations and work-management views are orange, Projects is yellow, and Settings is red. The selected tab adds a restrained glow.
Where Themes Are Stored
Themes are JSON files under your ThinkForge data root:
Themes\built-in\— the shipped presets, written on first launch. Read-only.Themes\custom\— your own and imported themes.
An installed copy stores these under Documents\Think Forge.
Because themes are plain files, they can be copied between machines. The Theme Editor also has explicit import and export.
Chrome Extension Themes Are Separate
The Chrome extension has its own theme settings. Changing a preset in the desktop app does not change the extension, and vice versa. Set the extension's theme under its Settings > Appearance.
Editor Theming
Document colors — body text, headings, links, code block backgrounds, blockquote borders, and horizontal rules — are part of the theme.
The rich-text editor currently uses fixed colors for these elements, so its document colors may differ from the active theme.
