/**
 * A scheme that places the source color in Scheme.primaryContainer.
 *
 * 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.
 *
 * 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.
