Why Is The Sky Blue?

When I wake up in the morning, first I open up my eyes,
 Then I open up my window, and look up at the skies.
 And I hope it's blue ---
 Clouds: Blue, blue, blue
 The sky is blue ---
 Clouds: Blue, blue, blue ---
 Blue is my favorite berry
 The color of the sky,
 so is necessary Light blue, dark blue, the shades may vary
 Blue is a color that we call primary
 Blue for eyes, blue is cold
 Blue is the water in the swimming pool, uh huh
 Blue is the ocean that you sail
 You might see a blue beard, or a big blue whale
 Blue for birds, blue for sad
 The screen when you know your computer crashed
 Blue for the moon, and blue jeans too
 So the first thing that I doW -
 When I wake up in the morning, first I open up my eyes
 Then I open up my window, and look up at the skies
 And I hope it's blue ---Clouds: Blue, blue,
 blueThe sky is blue ---Clouds: Blue, blue, blue
