Hi Jeremy, thanks for your question.
This seems like a good opportunity for our team to create some kind of technical documentation to share how this works. I can take that back to our team to put on our roadmap. I was thinking a tech note or blog post. Would that work for you?
To build on what others have said, starting in 11.1.1 there is a property called "Colour consistency" that will assign the same colour to the same projected value across all your visualizations of the same dashboard. Think of this as 'system-assigned-colour-by-value'; when this property is enabled you will see that anywhere a value (eg. "Texas") appears on a visualization, it appears as the same colour.
Looking ahead, future iterations of this experience would be 'customer-assigned-colour-by-value'; giving you more control over colour assignment. With this, you would see "Texas" coloured with the same colour across all your visualization, and you get to choose the colour. So you could have "Texas" appear everywhere in your dashboard as burnt orange, or maroon, or whatever colour you think best represents "Texas".
You can vote to let us know 'customer-assigned-colour-by-value' matters to you, or submit your own ideas of how to improve this experience in our Ideas portal.

Subject: Dashboard Visualization Color Inconsistencies
Hi,
I am trying to understand how dashboard visualizations determine what colors to use in a palette. Maybe this is a bug or just the way I am performing the task. As an example, I created two area charts. They have two measures on the y-axis which creates a color group. The result is one chart is using the first and second color of the palette while another might use the last two colors or the exact same palette.
Has anyone else seen/resolved this?
Thanks.
