# Enhanced colorization

The Visual Studio Code C/C++ extension now supports semantic colorization, when IntelliSense is enabled.  Use of enhanced colorization is controlled by the C_Cpp.enhancedColorization setting.  This setting is enabled by default.

```json
"C_Cpp.enhancedColorization": "enabled"
```

## Themes

Colors can be associated using the existing support for theming and color customization in VS Code.  See the [VS Code Themes documentation](/docs/configure/themes.md) for more information.

Colors are associated with [semantic tokens](https://code.visualstudio.com/api/extension-guides/color-theme#semantic-colors) as well as [TextMate scopes](https://macromates.com/manual/en/language_grammars#naming_conventions).

### C/C++ Themes Extension

We've created a set of VS Code themes that closely resemble the default Light and Dark themes in Visual Studio, and include colors for semantic tokens.  These themes can be found [here](https://marketplace.visualstudio.com/items?itemName=ms-vscode.cpptools-themes).

## IntelliSense Tokens and Scopes

| Token | Semantic Token name | Fallback TextMate Scope |
| ------------- |:-------------:|:-------------:|
| Class Template | templateType | entity.name.type.class.templated |
| Enumerator | enumMember | variable.other.enummember |
| Event (C++/CLI) | event | variable.other.event |
| Function | function | entity.name.function |
| Function Template | templateFunction | entity.name.function.templated |
| Generic Type (C++/CLI) | genericType | entity.name.type.class.generic |
| Global Variable | variable.global | variable.other.global |
| Label | label | entity.name.label |
| Local Variable | variable.local | variable.other.local |
| Macro | macro | entity.name.function.preprocessor |
| Member Field | property | variable.other.property |
| Member Function | method | entity.name.function.member |
| Namespace | namespace | entity.name.namespace |
| New / Delete | newOperator | keyword.operator.new |
| Operator Overload Function | operatorOverload | entity.name.function.operator |
| Operator Overload Member | memberOperatorOverload | entity.name.function.operator.member |
| Parameter | parameter | variable.parameter |
| Property (C++/CLI) | cliProperty | variable.other.property.cli |
| Reference Type (C++/CLI) | referenceType | entity.name.type.class.reference |
| Static Member Field | property.static | variable.other.property.static |
| Static Member Function | method.static | entity.name.function.member.static |
| Type | type | entity.name.type |
| User-Defined Literal - Number | numberLiteral | entity.name.operator.custom-literal.number |
| User-Defined Literal - Raw | customLiteral | entity.name.operator.custom-literal |
| User-Defined Literal - String | stringLiteral | entity.name.operator.custom-literal.string |
| Value Type (C++/CLI) | valueType | entity.name.type.class.value |

## Customizing Colors in Settings

Colors can also be overridden globally, in settings:

```json
    "editor.semanticTokenColorCustomizations": {
        "rules": {
            "templateType": {
                "foreground": "#ff0000",
                "fontStyle": "italic bold underline"
            }
        }
    }
```

Or, overridden on a per-theme basis:

```json
    "editor.semanticTokenColorCustomizations": {
        "[Visual Studio Dark]": {
            "rules": {
                "templateType": {
                    "foreground": "#ff0000",
                    "fontStyle": "italic bold underline"
                }
            }
        }
    }
```
