in Thoreau’s Journal:

Sitting by the road beyond N. Barrett’s, the colors of the world are: overhead a very light blue sky, darkest in the zenith, lightest in the horizon, with scattered white clouds seeming thickest in the horizon; all around the undulating earth a very light tawny color, from the dead grass, with the reddish and gray of forests mingled with evergreen; and, in the lap of earth, very dark blue rippled water, answering to the light blue above; the shadows of clouds flitting over all below; the spires of woods fringing the horizon on every side, and, nearer, single trees here and there seen with dark branches against the sky.
