+/**
+ * A scheme that places the source color in Scheme.primaryContainer.
+ *
+ * <p>Primary Container is the source color, adjusted for color relativity. It maintains constant
+ * appearance in light mode and dark mode. This adds ~5 tone in light mode, and subtracts ~5 tone in
+ * dark mode.
+ *
+ * <p>Tertiary Container is an analogous color, specifically, the analog of a color wheel divided
+ * into 6, and the precise analog is the one found by increasing hue. This is a scientifically
+ * grounded equivalent to rotating hue clockwise by 60 degrees. It also maintains constant
+ * appearance.
