def ask(statement, color = nil)
  raise NotImplementedError, "Implement #ask for Thor::Shell::HTML"
end
set_color (string, *colors)

Set color by using a string or one of the defined constants. If a third option is set to true, it also adds bold to the string. This is based on Highline implementation and it automatically appends CLEAR to the end of the returned String.

# File lib/thor/shell/html.rb, line 54
def set_color(string, *colors)
  if colors.all? { |color| color.is_a?(Symbol) || color.is_a?(String) }
    html_colors = colors.map { |color| lookup_color(color) }
    "<span style=\"#{html_colors.join('; ')};\">#{Thor::Util.escape_html(string)}</span>"
  else
    color, bold = colors
    html_color = self.class.const_get(color.to_s.upcase) if color.is_a?(Symbol)
    styles = [html_color]
    styles << BOLD if bold
    "<span style=\"#{styles.join('; ')};\">#{Thor::Util.escape_html(string)}</span>"
  end
end
