Abstract
The contrast definitions of opposite colors red-green and blue-yellow, which have been described in the CIELAB and YCrCb color spaces, respectively, and a method to accurately control chroma and color differences on a cathode ray tube screen are presented according to the color display characteristics of cathode ray tubes. Using target gratings on a cathode ray tube screen, measurements of human vision contrast sensitivity to red-green and blue-yellow colors for 10 spatial frequencies (0.41, 0.82, 1.23, 1.97, 3.08, 3.79, 4.93, 7.04, 9.86 and 16.43 cpd) were carried out in 11 young observers in a dark environment. Contrast sensitivity functions of opposite colors were obtained, which can be used for practical applications in image technologies.
