Examples:
'Message'.bold.white.on_green -> #{'Message'.bold.white.on_green}
'Message'.colorize({mode: :bold, color: :white, background: :green}) -> #{'Message'.colorize({mode: :bold, color: :white, background: :green})}

IMPORTANT: colorize() is tetchy. It likes to fail silently! Check for:
1. Exactly one argument, a Hash. NOT keyword args!                      | Bad: #{'s.colorize(color: :red)'.red}         | Good: #{'s.colorize({color: :red})'.green}
2. All values are symbols. NOT strings!                                 | Bad: #{'s.colorize(color: "red")'.red}        | Good: #{'s.colorize(color: :red)'.green}
3. Background color is just the color name, it does NOT begin with on_. | Bad: #{'s.colorize(background: :on_red)'.red} | Good: #{'s.colorize(background: :red)'.green}
