Now, researchers have discovered that hot chocolate "tastes" better if it is in an orange or cream colored cup. According to the Wall Street Journal, "Researchers in Europe asked 57 participants to assess the taste of hot cocoa served in four different colored cups, all the same size: white, cream, orange and red." By a large margin, the volunteers perceived the beverage to be much flavorful when served in the orange or the cream colored cups.
The same study also confirmed that other food and beverage container colors enhanced taste. Yellow tins improved the flavor of lemon and pink packaged drinks were perceived as being more sugary.
