Yellow carnations symbolize disappointment. As a whole, carnations are meant to show love or to answer a question. A striped carnation, for example, gives an answer of "No," while a solid carnation gives an answer of "Yes."
Carnations are very fragrant flowers that have vibrant colors. An arrangement of carnations can show all the emotions of love, such as white for pure love, red for deep love and pink for a love not to be forgotten. These flowers are sometimes used to show sympathy at funerals, especially when they are combined with other carnations, such as white or red carnations.
