    A computer program developed for a color screen often is useless when applied to monochromatic monitors. The problem resides in adequate palette selection. A simple method to adjust the RGB component's chromatic sample levels in analog video in order to get specified levels of luminance that will hide some of the samples when viewed on a nonchromatic monitor is presented View full abstract»
