Ishihara Color Test

Famous quotes containing the words color and/or test:

    African rights and liberty is a subject that ought to fire the breast of every free man of color in these United States, and excite in his bosom a lively, deep, decided and heart-felt interest.
    Maria Stewart (1803–1879)

    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)
