Conditional Formatting with a Legend

Hi 0Experience 

Thank you for the thorough explanation. Currently, in Power BI, when a visual uses a legend for multiple series, the legend determines the color assignment for each series. As a result, conditional formatting for data colors using DAX measures or field values may not be available, as it is overridden by the legend.

See this reference: https://learn.microsoft.com/en-us/power-bi/visuals/power-bi-visualization-conditional-formatting#co…

For cases where you need consistent colors across visuals and pages, using a Report Theme (JSON) is recommended. This approach centralizes the color palette and helps maintain consistency, though colors are assigned based on the series order and may change if legend values are filtered.

If you need fully dynamic, data-driven color control while keeping the legend (including in Focus Mode and exports), native Power BI visuals do not currently support this. In such situations, a custom visual like Deneb can be used to explicitly map colors and retain a functional legend.
