Why is the Blue Mountains blue?

Here is my version:

On the day that God created the earth, He also created the vast ocean and the mountains. He created them so that every living creature would be perfect in its place. He created the fishes and painted them with all the different colors of the rainbow. He created the birds so that every ray of light that reflects them would stare in awe of their beauty. He took so much time to define every detail of every creature. Everything was so delicate and seems so perfect. But then, God became so tired, He fell asleep for some minutes. He got tired and took a quick nap.

Because of his tiredness, he forgot to color the vast ocean and the mountains. Every fish and every bird had been colored beautifully, but their home, the ocean and mountains had no color. The ocean and the mountains were all black. When God woke up from His slumber, He accidentally bumped the pail of color blue. So everything in its way that were pitch black became blue. Henceforth, the ocean and the mountains were blue. And so the blue mountains!
