fleckless

Then the sky resumes the fleckless blueness which characterises it during the greater part of the year.

Out of the blue void of a fleckless sky, came whooping at dawn a boisterous wind.

A vast sweep of fleckless azure overhung the glistening plain below.

The papers extended across the hall and into a prim, fleckless parlor.

The sky was fleckless by this time and it did not seem possible that another storm could come up.
