title: [Work of the human visual system. VII. Opposite color difference and anticolor. 4th series of experiments].
abstract: The "opposite color differences" were considered in the case of decreasing of color difference, when k ln a2 a1 was changed to k ln a2+a3 a1+a3 and in the case of disappearance of color difference, when k ln a2 a1 was changed to k in a3 a3. It is shown that the changes indicated evoke the appearance of correlated opposite color differences; k is the coefficient of proportionality with a dimension of sensation; a1, a2 and a3 are the actions of light.
