White: Purity, Innocence, Sympathy, Spirituality

Early tradition used white roses as a symbol for true love, an association which would later become the hallmark of the red rose. Also known as the bridal rose, the white rose is a traditional wedding flower. In this sense, white represents unity, virtue, and the pureness of a new love. White roses are also associated with honor and reverence, which makes them a fitting memorial for a departed loved one.

Perfect for: Your wife (first day of marriage); that weird neighborhood kid who always wears a cummerbund; your wife (last day of marriage.)

Orange: Desire, Enthusiasm and Passion

A literal mixture of yellow and red, orange roses were seen as a bridge between friendship symbolized by yellow roses and love represented by red roses. They can be an expression of fascination, or a gift to say 'I'm proud of you.'

Perfect for: Halloween honeymoons; minor academic achievements (first A-, graduation from butcher academy, etc.); subtly hitting on married people.
