Whether you are dyeing a green beer for St. Patrick's Day, mixing up a blue Hawaiian or simply colouring your party's punch, adding food colouring to a drink gives it a customised colour of your own choosing. While food colouring won't change the taste of your drink, it makes it look festive in whatever colour of the rainbow you want.
Tilt your glass and slowly pour your drink to avoid building up a foamy head.
Drop in six drops of blue food colouring while slowly stirring to achieve a dull, olive green colouring.
Pour another glass.
Drop in six drops of green food colouring while slowly stirring for a bright, sparkly emerald green colouring.
Mix a shot of coconut rum in a glass with ice, pineapple juice and a splash of soda.

Add more food colouring for a bolder blue tint.
Coloured Party Punch
Mix a batch of coloured party punch by adding food colouring quickly to a prepared bowl of the drink -- instead of squirting one drop at a time, squirt a steady stream of the colouring while stirring the mixture.
Stir the mixture throughout the party to prevent the contents from settling.
Place different containers of food colouring near the empty glasses and do not add dye to communal punch bowl -- this way, guests can add colouring to their own drinks for personalised concoctions.
Don't try adding green colouring to darker beers like stouts -- it takes too much food colouring and will dye your mouth.
