If the meadows were untouched, I should no doubt see many more of the rare white and the beautiful smaller purple orchids there, as I now see a few along the shaded brooks and meadow's edge.—Journal, 29 July 1853
In reality, history fluctuates as the face of the landscape from morning to evening. What is of moment is its hue and color. Time hides no treasures; we want not its then, but its now. We do not complain that the mountains in the horizon are blue and indistinct; they are the more like the heavens.—A Week on the Concord and Merrimack Rivers
Instead of the white lily, which requires mud, or the common sweet flag, the blue flag (Iris versicolor) grows thinly in the pure water, rising from the stony bottom all around the shore, where it is visited by hummingbirds in June . . .—Walden
It is remarkable that no pains is taken to teach children to distinguish colors. I am myself uncertain about the names of many.—Journal, 28 January 1852
It will have some red stains, commemorating the mornings and evening it has witnessed; some dark and rusty blotches, in memory of the clouds and foggy, mildewy days that have passed over it; and a spacious field of green reflecting the general face of Nature,—green even as the fields; or a yellow ground, which implies a milder flavor,—yellow as the harvest, or russet as the hills.—"Wild Apples"
Looking southward, the heavens were completely overcast, the mountains capped with clouds, and the lake generally wore a dark and stormy appearance, but from its surface six or eight miles distant there was reflected upward through the misty air a bright blue tinge from the unseen sky of another latitude beyond.—The Maine Woods
October is the month for painted leaves. Their rich glow now flashes round the world. As fruits and leaves and the day itself acquire a bright tint just before they fall so the year near its setting. October is its sunset sky; November the later twilight.—"Autumnal Tints"
Painted by the frosts, some a uniform clear bright yellow, or red, or crimson, as if their spheres had regularly revolved, and enjoyed the influence of the sun on all sides alike,—some with the faintest pink blush imaginable,—some brindled with deep red streaks like a cow, or with hundreds of fine blood-red rays running regularly from the stem-dimple to the blossom end, like meridional lines, on a straw-colored ground,—some touched with a greenish rust, like a fine lichen, here and there, with crimson blotches or eyes more or less confluent and fiery when wet,—and others gnarly, and freckled or peppered all over on the stem side with fine crimson spots on a white ground, as if accidentally sprinkled from the brush of Him who paints the autumn leaves.—"Wild Apples"
Seeing at that moment three little red birds fly out of a crevice in the ruins, up into an arbor-vitae tree, which grew out of them, I asked him their names, in such French as I could muster, but he neither understood me or ornithology . . .—A Yankee in Canada
So vivacious is redness. The very rails reflect a rosy light at this hour and season. You see a redder tree than exists.—"Autumnal Tints"
