“ I'd rather England became the 51st state of the U.S.A. than get tied up to there,” said a retired civil servant with a complexion the color of ruby port. 

“ 我宁愿英格兰成为美国的第51个洲，也不要跟法国连在一起，” 一位退休的公务员如是说，他的脸色红得就像红葡萄酒。 

请问“ with a complexion the color of ruby port”为什么不写成“ with a complexion of the color of ruby port”？原句的写法是否有误？ a complexion 和the  color 都是名词，插入of表从属不是更好吗？
