## Themes and fonts

The Color Scheme list changes the presentation of code and binary views, including the available dark theme.

Select a scheme under **Tools > Options > Personalize**. Choose a readable combination of foreground, background and syntax colors for long review sessions.

### Custom theme files

Presets are `.ini` files in the `colors` folder under the installation directory. The filename supplies the preset name. Copy an existing preset to create your own and preserve the keys you do not intend to change. A selected theme can be applied without restarting the application, including after editing its INI file.

The `[Colors]` section uses decimal color values. Its keys include `Background`, `Foreground`, `KeyWords`, `LocationsAndArguments`, `Procedures`, `UnderCursorBackground` and `UnderCursorForeground`. `UseDarkMode` selects a light (`0`) or dark (`1`) interface. `Colors2=1` enables the extended color section.

An excerpt using extended code-view settings:

```
[Colors]
UseDarkMode=1
Colors2=1

[Colors2]
TVFontName=Segoe UI, Tahoma, Arial
TVFontSize=10
FontName=Consolas, Courier New, monospace
FontSize=11
Background=1E1E1E
Foreground=DFDFE0
Key=CD9069
String=569CD6
HexFontName=Consolas, Courier New, monospace
HexFontSize=11
HexBackground=1E1E1E
HexForeground=DFDFE0
```

### Font and syntax settings

The basic `[Font]` section provides `Name`, `Size`, `KeyWordsBold`, `LocationsAndArgumentsBold` and `ProceduresBold`. In `[Colors2]`, font names can contain comma-separated fallbacks. Tree fonts use `TVFontName` and `TVFontSize`; code views use `FontName` and `FontSize`; the HEX Editor uses `HexFontName` and `HexFontSize`.

Extended colors use hexadecimal values. Syntax keys include `Key`, `Comment`, `Char`, `Float`, `Hex`, `Number`, `String` and `Symbol`. HEX Editor keys include `HexBackground`, `HexForeground`, `HexGrid`, `HexActiveFieldBackground`, `HexOffsetBackground`, `HexCurrentOffset`, `HexOddColumn`, `HexEvenColumn` and `HexOffset`. Under-cursor colors control matching-identifier highlighting in code.
