Confusing with Power BI Data Color

Hi, SarahHuang 

When there are multiple value fields, legend is automatically generated to distinguish different fields. So you cannot set conditional formatting.
The workaround is to use other visuals, such as matrix, so that you can apply conditional formatting to the fields.
Or apply conditional formatting to data labels in Clustered Bar.
Or create 2 Clustered Bar with one value field.

Result:

Hope this helps.
