★★ A wide band of pale blue separated the sharp purple hills at the horizon from the frayed purple edge of the cloud sheet above. The hills stayed purple while the clouds became wrinkled and dimpled gray. Perfect clarity took over for a spell, but then the lid came down again, with murky tints of brown and orange on it. A wind blew insistently, then forcefully, from uptown. Only the gaudiest athletic-green accents stood out on the clothes and gear of the children on the dim playground.
