/**
* 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.
