Only the eyes and hands were visible in the gray cloud.

Above them, all I could see was thick gray cloud.

The road was wet and there were gray clouds ahead.

His whole figure soon came into view against the background of grey cloud.

The air was fresh, but they were under low, gray clouds this morning.

But there were gray clouds ahead, to the right and below.

The sun was moving out from behind a gray cloud.

Sometimes gray, but blue if there aren't clouds and it is day.

It was, more or less, gray clouds and not much else.

I can see what looks like a grey cloud coming this way.
