Color Picker for generating sml and RGB values with hue angles on an iso-luminance plane, and vice versa.
Advanced features:
- switch color depths;
- adjust the iso-luminance plane for single subjects;
- generate display-realizable hue lists
- display a color circle
:param gray_level: default is 0.66
:param c: contrast (i.e. chromaticity since we use iso-luminance); no larger than 0.155; default is 0.12
:param sscale: just for better viewing, usually no need to change; default is 2.6
:param unit: hue angle unit: radian[default] or degree
:param depthBits: color depth: 8[default] or 10
:param subject: perform subjective adjustment if not None. Subject isolum files will be searched and used.
