The Noun thats most vivid picture

Coral is the most vivid picture because he compares it to her lips by saying" Coral is far more red thatn her lips". I can really picture this is my mind because back in Shakesphere's time women were highed breasted with often red lips and rosy cheeks. So I can actual understand why he said coral is more red than her lips because women's lips are usually red and I guess her wasn't.
