W. A. Hawley, Oriental Rugs, Antique and Modern
“ In all of the antique carpets that remain and in very many rugs over fifty years of age, all the colours employed in a single piece are in tones of perfect harmony, and are so placed with reference to one another that the effect is most agreeable. But in some of the modern pieces, such as are produced in parts of Asia Minor and Caucasia, are colours which, like discordant notes of music, grate harshly on the senses. The most pleasing effect is when colours of border and field are complementary, yet so in harmony as to accentuate the qualities of each. ”
