Ishihara Color Test

Famous quotes containing the words color and/or test:

    To face the garment of rebellion
    With some fine color that may please the eye
    Of fickle changelings and poor discontents.
    Which gape and rub the elbow at the news
    Of hurly-burly innovation.
    William Shakespeare (1564–1616)

    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)
