/**
 * CompositionLocal containing the preferred content color for a given position in the hierarchy.
 * This typically represents the `on` color for a color in [ColorScheme]. For example, if the background
 * color is [ColorScheme.surface], this color is typically set to [ColorScheme.onSurface].
 *
 * This color should be used for any typography / iconography, to ensure that the color of these
 * adjusts when the background color changes. For example, on a dark background, text should be
 * light, and on a light background, text should be dark.
 *
 * Defaults to [Color.White] if no color has been explicitly set.
