The confusion points of dichromats are derived from the constant-luminance planes of trichromats, protanopes and deuteranopes experimentally defined by heterochromatic-flicker photometry: (1) the zero-luminance planes of the observers considered in this experiment intersect almost exactly in a line that crosses the plane of the chromaticity diagram in the tritanopic-confusion point and confirm that the short-wavelength sensitive cones can be considered to have no contribution to luminance; (2) protanopic- and deuteranopic-confusion points are taken as being defined by the intersection of the tangent line to the long-wavelength region of the spectrum locus and the zero-luminance plane for protanopes and deuteranopes, respectively.
二色视者的混淆点源自三色视者、红色盲者和绿色盲者通过异色闪烁光度法实验确定的恒定亮度平面：(1) 本实验中所考虑的观察者的零亮度平面几乎精确地相交于一条穿过色度图平面上蓝黄色盲混淆点的直线，这证实了短波敏感视锥细胞对亮度几乎没有贡献；(2) 红色盲和绿色盲的混淆点分别由光谱轨迹长波区域的切线与红色盲者和绿色盲者的零亮度平面的交点确定。
