小美吃彩虹糖：不同颜色组合带来的喜悦天数计算

以下是一个解决这个问题的Python代码： ```python def count_happy_days(candies): combinations = set() happy_days = 0 for i in range(len(candies)-1): for j in range(i+1, len(candies)): combination = (candies[i], candies[j]) if combination not in combinations: combinations.add(combination) happy_days += 1 return happy_days candies = [1, 1, 4, 5, 1, 4] result = count_happy_days(candies) print(result) ``` 运行这段代码，输出结果为3，表示小美最多有3天会很高兴。
