For many years, I have been moved by the blue at the far edge of what can be seen, that color of horizons, of remote mountain ranges, of anything far away. The color of that distance is the color of an emotion, the color of solitude and of desire, the color of there seen from here, the color of where you are not. And the color of where you can never go.

… It's hard to say whether it was pain or the past that was being extirpated or whether they were the same thing. The doctors who treated her were unlikely to have experienced such profound instability: disappearing mothers, the vast gap between the medieval Russian-Polish Pale and glittering amnesiac Los Angeles, the three or four languages she left behind and the English she never completely acquired, the annihilation of the world she came from and of the relatives she left behind. Post-traumatic stress disorder is an alternate diagnosis a therapist once proffered for her behavior, a condition that recognized all the kinds of war she survived and a world in which nothing was too far-fetched or terrible to be possible.
The word "lost" comes from the Old Norse los, meaning the disbanding of an army, and this origin suggests soldiers falling out of formation to go home, a truce with the wide world. I worry now that many people never disband their armies, never go beyond what they know. Advertising, alarmist news, technology, incessant busyness, and the design of public and private space conspire to make it so.
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 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 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 that 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.
