“Colorblind Dark” — the color-vision-deficiency-safe Okabe-Ito palette on a dark ground. Reuses the light theme’s palette (lifting its black entry so it reads on the dark ground) and applies a neutral dark set of interface colors.

“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).

“Dataviz Dark” — the Dataviz palette on a dark ground. Reuses the Dataviz series colors (lifting any too-dark entries so they read on the dark ground) and applies a neutral dark set of interface colors.

“Ember” — a warm dark theme on a warm near-black ground, with a series palette biased toward ambers, oranges and reds (plus a few cool hues for categorical separation).

“Frozen Dark” — the icy Frozen palette on a dark ground. Its pastels are already bright, so the palette comes through essentially unchanged; only a neutral dark set of interface colors is applied.
