Blue gives us the beauty.

The world is blue at its edges and in its depths.

This blue is the light that got lost. Light at the

blue end of the spectrum does not travel the

whole distance from the sun to us. It disperses

among the molecules of the air, it scatters in the

water. Water is colorless, shallow water appears

to be the color of whatever lies underneath it, but

deep water is full of this scattered light, the purer

the water the deeper the blue. The sky is blue for

the same reason, but the blue at the horizon, the

blue of the land that seems to be dissolving into

the sky, is a deeper, dreamier, melancholy blue,

the blue at the farthest reaches of the places where

you see for miles, the blue of distance. This light

does not touch us, does not travel the whole

distance, the light that gets lost, gives us the

beauty of the world, so much of which is

in the color blue.
