It would be very helpful to have a way to automatically sync visualization color schemes between different visualizations to match each other. I am aware of the functionality that currently exists to apply colors to visualizations or set colors from another visualization, but this is a one time effect that does not update whenever the color scheme is changed in another visualization. It would save a lot of time if there was a built in way for a visualization to reference another visualization's color scheme so that any changes made to the one color scheme will affect any other visualizations that reference the same color scheme. It may even make sense to add a feature similar to markings and filtering schemes that contain the colors for a given column of categorical data and could be referenced directly by a visualization.
