Ishihara Color Test

Famous quotes containing the words color and/or test:

    The intellect,—that is miraculous! Who has it, has the talisman: his skin and bones, though they were of the color of night, are transparent, and the everlasting stars shine through, with attractive beams.
    Ralph Waldo Emerson (1803–1882)

    It is commonly said, and more particularly by Lord Shaftesbury, that ridicule is the best test of truth; for that it will not stick where it is not just. I deny it. A truth learned in a certain light, and attacked in certain words, by men of wit and humour, may, and often doth, become ridiculous, at least so far, that the truth is only remembered and repeated for the sake of the ridicule.
    Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
