That colour never appeals to him. In his opinion, violet doesn't appeal to anyone. However, the law states all restaurants have to be violet. Doors, windows, curtains and even the synthetic marble on the floors must be violet. You can tell what sorts of food will be available from the different shades of the colour. A very light violet would imply that the particular testaurant has nothing other than drinks. A dark violet would mean the restaurant is the best place for a full meal.
