One of the most requested Elastic Maps features is the ability to define/customize a color palette for categorical data.

The Maps team would like to solve this problem with a solution that spans Kibana applications, so that categorical values are styled consistently across embedded panels. When a category value is symbolized as a blue marker on the Map, the same category value is also symbolized as a blue bar in a bar chart, and a blue pie slice in a pie chart and so on.

The Maps team would like a solution where users can define the color palette once and use the same color palette across any embeddable that is symbolizing the same set of values. Embeddables should use the pre-defined color palette by default so data is symbolized consistently by default. Embeddables can allow local modifications to the color palette to satisfy user needs.

The Maps team would like to put a POC forward to move the conversation into an implementation. Today, Index Patterns are the only way to share field meta data across Kibana. We would like to enhance Index Pattern field's with an optional property, Color Palette.
