This annihilation of colors is called achromatism.    From LearnThat.org.  [http://www.bc.edu/bc_org/avp/cas/fnart/fa257/blanc_color.html]

Very occasionally a person lacks all color-receptors and is completely color-blind, a condition called achromatism (ay-kroh'muh-tiz-um; "no color" G).    From Wordnik.com.  [The Human Brain]

Although this peculiar disharmony in the dispersive powers of the two glasses, crown and flint, was discovered almost immediately after achromatism was invented, it was only recently that the first successful attempts were made to produce different glasses, which, possessing the other requirements for achromatic objectives, would produce coincident spectra, or nearer so than the ordinary crown and flint glass do.    From Wordnik.com.  [Scientific American Supplement, No. 561, October 2, 1886] Reference

As the diameter of the lens was so small in comparison with its focal length, its want of achromatism was inappreciable.    From Wordnik.com.  [Experimental Determination of the Velocity of Light Made at the U.S. Naval Academy, Annapolis] Reference

A long list of indictments might indeed be brought against the eye -- its opacity, its want of symmetry, its lack of achromatism, its partial blindness.    From Wordnik.com.  [Six Lectures on Light Delivered In The United States In 1872-1873] Reference

And the mere fact that the problem of achromatism was solved by "the mind of a sagacious optician inquiring how this matter was managed in the eye," no more proves that.    From Wordnik.com.  [A Candid Examination of Theism] Reference

True achromatism cannot be obtained with ordinary flint and crown-glass; and although in lenses of "Jena glass," outstanding colour is reduced to about one-sixth its usual amount, their term of service is fatally abridged by rapid deterioration.    From Wordnik.com.  [A Popular History of Astronomy During the Nineteenth Century Fourth Edition] Reference
