Autumn alights with bright-tinted shrubs. And yes, you need to be on the alert to perceive their full beauty.
‘A passer-by might, perhaps would, have noticed that the bright-tinted shrubs about the high shore on the sunny side were reflected in the water; but, unless on the alert for such effects, he would have failed to perceive the full beauty of the phenomenon.’ 7 Oct 1857
