What is colouring material?

Famous quotes containing the words material and/or colouring:

    Who shall set a limit to the influence of a human being? There are men, who, by their sympathetic attractions, carry nations with them, and lead the activity of the human race. And if there be such a tie, that, wherever the mind of man goes, nature will accompany him, perhaps there are men whose magnetisms are of that force to draw material and elemental powers, and, where they appear, immense instrumentalities organize around them.
    Ralph Waldo Emerson (1803–1882)

    The innocent brightness of a new-born Day
    Is lovely yet;
    The Clouds that gather round the setting sun
    Do take a sober colouring from an eye
    That hath kept watch o’er man’s mortality;
    William Wordsworth (1770–1850)
