The world was made of grey
No colors at all
And all I can say
Is that the color shattered on a wall
Walls had been grey forever
The color had no meaning
And as I pull a lever
The color appears for my well-being
Colors spread like a disease
With red, yellow, and brown
Give me some more colors please
Or I will surely frown
All these colors are made from grey
So thanks to grey, we have colors today
