I asked the little boy who cannot see,

"And what is colour like?"

"Why, green," said he,

"Is like the rustle when the wind blows through

The forest; running water, that is blue;

And red is like a trumpet sound; and pink

Is like the smell of roses, and I think

That purple must be like a thunderstorm,

And yellow is like something soft and warm;

And white is a pleasant stillness when you lie,

And dream!
