*the pure color of a clear sky; the primary color between green and violet in the visible spectrum, an effect of light with a wavelength between 450 and 500 nm.
*Feeling or showing sadness

Two definitions, One word.
If this is posible, why reaching the sky with your hands is not ?

I'm Blue and I have nothing to do, I'm alone and bored. So I came to tell some stories.
