Customize series colors using value from data dimension

My data has a dimension for a hex color, as a string.

It would be cool if I could apply this color to its respective series in the visualization.

This would allow me to color-encode the data in ways that are intuitive to the viewer (e.g. a pie chart of widgets sold, by color). It would also help the colors stay consistent across multiple visualizations in a dashboard, since the colors are applied programmatically. This would be true even if the number of series is dynamic and unpredictable.
