Why is the world so blue?

Question

The sea, the sky, 

the mountains, sometimes.

There's a blue note

& music genre (with coke).

Blue eyes over blue shirts. 

In many flags where freedom starts. 

Why is the world so blue

And who in the blue hell are you?

Answer 1

Why?

The world ain't colorblind

Time twists wasted on divine 

Lines and bright signs.

The world ain't no harmony

You can't sing on all keys,

Doors are hidden from thee.

The world ain't always true

Falsehoods are heard, too,

As plain gibberish soothes.

That's why the world is blue.

A song you just can't tune.

Answer 2

“Tell me why the stars do shine,

Tell me why the ivy twines,

Tell me what makes skies so blue,

And I'll tell you why I love you.

Nuclear fusion makes stars to shine,

Tropisms make the ivy twine,

Raleigh scattering make skies so blue,

Testicular hormones are why I love you. ” 

― Isaac Asimov
