General rules on use and registration of common colour names not applicable to 'indigo'

In Pearl Village Co Ltd v Department of Intellectual Property, the Supreme Court has overturned a judgment of the IP & IT Court and held that the mark INDIGO PEARL was confusingly similar to the registered mark HOTEL INDIGO. Among other things, the Supreme Court held that the general rules applicable to the use and registration of common colour names such as red and black did not apply to the colour indigo.
