CommandLine.Help.ColorScheme (picocli 4.7.6 API)

java.lang.Object
- picocli.CommandLine.Help.ColorScheme

Enclosing class:

CommandLine.Help
```
public static class CommandLine.Help.ColorScheme
extends Object
```
All usage help message are generated with a color scheme that assigns certain styles and colors to common parts of a usage message: the command name, options, positional parameters and option parameters. Users may customize these styles by creating Help with a custom color scheme.
Note that these options and styles may not be rendered if ANSI escape codes are not enabled.

From 4.0, instances of this class are immutable.
