A rose signifies a lot of things.
Love, lust, honor, friendship, death, and happiness. But it is always the color that gives the feeling along with the person whom has given it.
A bright red rose: love
A dark red rose: lust
A pink rose: passion
A black rose: death
A yellow rose: friendship
A purple rose: honor
And a orange rose for HAPPINESS.
Just make sure you use them all correctly.
Love it hope. :)
