Does The Color Of Cups Affect People's Rating Of Coffee?

The experiment demonstrate that the color of cups affects people’s rating of coffee. I remember when I did this experiment on Jenny, one of the teachers in THSI, she was surprised by the different flavor in different cups. I accepted some of my hypothesizes, and some is still unsure. The glass cup can provide the strongest feeling to the testee. And, the dark blue cup can enhance the sensation of either sweetness and bitterness. Besides, due to the close percentage between blue and white cup, it can not prove that white cup is more bitter and it has thicker concentration than other cups. When I did this experiment, initially, I wanted the testee to rank their feeling of bitterness and sweetness. Then, I noticed that the difference between
each individuals result in the difference taste of the coffee, such as someone will not think the coffee has a bitter taste, but they may taste sweet. So, the method of ranking one by one can not be worked. I changed the method of recoding the data to allow the testee to rank “freely”, which they don’t need to follow the number, ranking from one to three, they would try their best to provide feelings and information for me. Due to the close percentage of bitterness and sweetness of the white and blue cups, one of the hypothesizes cannot be proved obviously. If I have chance to redo this experiment, I would like to have more time and test on more people. This result can actually apply in the manufacture of mugs. Cups of coffee are consumed in cafés, restaurants and other outlets each and every day. Producing different colored mug to target different group of people can give economic incentive to drinking coffee and profit to the café owners and factories(Doorn).
