asSparkColors
Converts a Material ColorScheme to a SparkColors instance.
This function adapts the color values from a Material Design ColorScheme to the structure and naming conventions used by SparkColors. The following tokens SparkColors.mainVariant, SparkColors.accentVariant, SparkColors.supportVariant and their on counterparts have no equivalent in Material so their are juste derivative of their principal token with a different tone that needs to be different for each (90/10 or 10/99). It handles both light and dark themes by adjusting the color tones accordingly.
Return
