/**
 * "Colorblind" — a color-vision-deficiency-safe qualitative palette based on
 * the Okabe-Ito eight-color set, which stays distinguishable under the common
 * forms of color blindness (protanopia, deuteranopia, tritanopia).
 *
 * Like `Dataviz` and `Kelly`, this theme only sets the series palette; it does
 * not change interface colors, so it layers cleanly on top of the default
 * (light) look. The canonical Okabe-Ito order leads with black; here the eight
 * colors are re-ordered to lead with color so the first series reads as a hue,
 * with black kept in the set for later series.
 *
 * @see {@link https://jfly.uni-koeln.de/color/} for the original palette
 * @see {@link https://www.amcharts.com/docs/v5/concepts/themes/} for more info
