Temporary bleaching of color centers in additively colored KBr and KCl crystals are investigated. The first and the second absorption bands of M center are bleached by F -light or M -light irradiation at 90°K. Accompanying with the bleaching of the M band, two absorption bands grow at 555 mµ and 780 mµ in KBr and at 505 mµ and 690 mµ in KCl. These bands as well as the bleached M bands show dichroism when the original M band is dichroic. The oscillator strengths of these bands are determined with respect to the M band, and discussions on the nature of the bands are made.
