Into the Blue

What does it mean when one says he is blue?

 Do colors define the state of the mind?

Must then we describe the shade or the hue?

And what is said if you speak to the blind?

One could be azure, as blue as clear skies,

and end his refrain with eyes filled with tears.

Be he then happy or his heart decries

his lover’s affection now veers.

What then of turquoise or aquamarine?

They’re hues of blue and fair to behold,

but no sage nor saint would know what you mean

 if that was the aura some said he showed.

Blue hues may belong on flowers or walls

but blue on a psyche renders shortfalls.
