Her color of blue is not the color of serenity,
neither the color of the calm sky
nor the color of the cool oceans

Her color of blue is black and gray
A sad blue eyes and a faint smile
A heavy heart and a wandering soul

Her color of blue is sadness,
unhappy
melancholy

So tell me,
how come the color of blue depicts peace and calmness?
When the other meaning of it is the opposite?
