Foundations
Categorical, sequential, diverging, semantic, and density color scales for charts — validated for colorblind-safe separation in both themes.
Categorical
The same 14-step categorical palette used in Colors. Charts draw series colors from this set, in order, and never cycle or reassign a color when a filter changes the series count.

Sequential
One hue, light → dark, for continuous magnitude (heatmaps, choropleths). The lightest step recedes toward the surface on purpose.

Diverging
Two hues with a neutral gray midpoint, for polarity around a meaningful zero.

Semantic (status)
The same alert severity scale used in Colors — reserved for state, never reused as a series color, and always paired with an icon and label.

Opacity steps of a single hue, for point/cell density (calendar heatmaps, contour fills).
