Hot chocolate tastes better in an orange colored cup.
Two researchers from the Polytechnic University of Valencia and the University of Oxford have proven that hot chocolate tastes better in an orange or cream colored cup than in a white or red one. They conducted an experiment in which 57 participants had to evaluate samples of hot chocolate served in four different types of plastic cup. They were the same size but of different colors: white, cream, red and orange with white on the inside. The results reveal that the flavor of chocolate served in orange or cream colored cups was better for the tasting volunteers.
