The sea was a gray blur beneath his plane as he raced toward the south.
Again, the same gray blur, only slightly different this time.
The world vanished in a gray blur of absolute speed.
With any luck, he would be a short grey blur in their memories.
Even with the glasses, it still looked like a grey blur to him.
Those things done, she sat against the door, gasping, the world a gray blur.
The screen came to life, but it was only a gray blur.
