Cheerleaders danced, music blared and fireworks were blasted into the grey sky, but it was all slightly sterile.

It's midday, with a great dome of cold grey sky.

Flocks of dark little teal went speeding across the grey sky.

Red deer stags moved along the ridge a thousand feet overhead, only their antlers visible against the grey sky.

A grey river cutting through a flat, featureless landscape beneath a grey sky.
