Things You'll Need
Bottled beer (light-colored beers work best)
Food coloring (various colors)
Whether you are dyeing a green beer for St. Patrick's Day, mixing up a blue Hawaiian or simply coloring your party's punch, adding food coloring to a drink gives it a customized color of your own choosing. While food coloring won't change the taste of your drink, it makes it look festive in whatever color of the rainbow you want.
Tilt your glass and slowly pour your drink to avoid building up a foamy head.

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