Creating Themes

User themes are loaded from JSON files (with the .bntheme extension) found in the themes or community-themes (consider cloning the community themes repo) subdirectories of your user folder. The default, full path to these folders is the following on each supported platform:

• macOS: ~/Library/Application Support/Binary Ninja/{themes,community-themes}
• Windows: %APPDATA%\Binary Ninja\{themes,community-themes}
• Linux: ~/.binaryninja/{themes,community-themes}

To get started, create a new .bntheme file in the themes folder for your platform. You may want to copy one of the example themes to start with to avoid lots of "missing required color" errors.

Theme File Structure

Theme files have the following top-level structure:

{
  "name": "Example Theme",
  "style": "Fusion",
  "styleSheet": "...",
  "colors": { ... },
  "palette": { ... },
  "disabledPalette": { ... },
  "theme-colors": { ... }
}

Name

The name key controls the theme's display name in the UI. This key must be unique. There cannot be multiple themes with the same name.

Style

The style key specifies which Qt style to use for the UI controls. This key should almost always be set to "Fusion".

Stylesheet

The styleSheet key can be used to customize the Qt style above with a stylesheet in Qt CSS syntax, like so:

{
  "styleSheet": "QWidget { border-radius: 0; }"
}

If you need to determine what a specific control's class is in order to style it, you can use the ui.uiDeveloperTools setting to enable the Widget Inspector.

Colors

The colors key allows you (the theme author) to define color aliases to be used throughout the rest of the theme file. For example, the following sets up two color aliases, red and blue:

{
  "colors": {
    "red": "#ff0000",
    "blue": [0, 0, 255]
  }
}

Colors can be specified as hex strings or as an [R, G, B] array.

Blending Functions

In addition to color aliases, the theming engine provides the ability to blend colors by passing an array of blending functions and arguments in prefix notation in place of a color. We provide two blending functions: average ("+") and mix ("~"), as seen in the example below:

{
  "colors": {
    "red": "#ff0000",
    "blue": [0, 0, 255],
    "purple": ["+", "red", "blue"],
    "yellow": "#ffff00",
    "white": [255, 255, 255],
    "slightPink": ["~", "white", "red", 20],
    "quitePink":  ["~", "white", "red", 200],
    "slightlyPinkYellow": ["+", "~", "white", "red", 20, "yellow"]
  }
}

In this example, red and blue are averaged (+) to create purple. Colors can also be mixed (~), in a weighted manner, like the slightPink and quitePink colors (which mix red into white using two different weights, specified by the integers at the end of the array). These blending functions can also be chained together, like in the slightlyPinkYellow color, which mixes some red into white and then averages the result with yellow.

Palette

The palette key is the primary interface for theming Qt UI elements and enables customization of the main QPalette color roles. The following sub-keys are required for all themes:

{
  "palette": {
    "Window": "...",
    "WindowText": "...",
    "Base": "...",
    "AlternateBase": "...",
    "ToolTipBase": "...",
    "ToolTipText": "...",
    "Text": "...",
    "Button": "...",
    "ButtonText": "...",
    "BrightText": "...",
    "Link": "...",
    "LinkVisited": "...",
    "Highlight": "...",
    "HighlightedText": "...",
    "Light": "..."
  }
}

The PlaceholderText sub-key is currently not themeable and will be automatically set to the "disabled" Text value specified below.

Disabled Palette

The disabledPalette key matches the palette key above, but specifies colors to use for disabled controls instead. While not required, providing entries for the Button, ButtonText, Text, WindowText, and ToolTipText roles is highly recommended.

Theme Colors

The theme-colors key contains the rest of a theme's settings. These colors are typically used for custom controls or contexts specific to Binary Ninja itself (which is why they are separate from the Qt colors controlled via the palette and disabledPalette keys above).

Colors marked "required" must be specified. Unmarked colors will hold default values based upon other colors you have chosen, but will be overridden if specified.
