  // Modify a previously colorized string.
  print('\nModify previously colorized strings:');

  // Create custom Anis modifier
  final customModifier = Ansi.combine({Ansi.yellow, Ansi.bold, Ansi.underline});

  // Replace first modifier:
  final yellowGreen = blueGreen.style(customModifier, method: Replace.first);

  // Replace all modifiers.
