Power BI: Highlight text using in DAX function

Hi guys, 

My stakeholders want to higtlight "Test Name", "WorkOrder" and "Product" in Details field when moving mouse to a point on the Line Chart as the screenshot. 

The below DAX function I use to concatenate three columns for "TestName", "WorkOrder" and "Product" .

Is there any way to modify the DAX function to hightlight "TestName", "WorkOrder" and "Product", the blue for example?

TestName_WO_Prod = "Test Name: " & Fact_Result[Test Name] & " | WorkOrder: " & RELATED(Dim_Product[WorkOrder]) & " | Product: " & RELATED(Dim_Product[Product Description])
