title: Uniform-scale chromaticity diagram with angular coordinates in zero-curvature space.
abstract: Dichromats have angular color discrimination in the usual chromaticity diagrams. Normal trichromatic vision is obtained by combining tritanopic and deuteranopic vision. In this paper, a new pair of angular variables is introduced from which, by a suitable transformation, a uniform-scale chromaticity diagram in zero-curvature space is obtained.
