Conditional colour format on data card

Hi Anonymous, this is a multistep process.

1. Compute a measure that returns your color selections. I used this:

Vs Average = 
VAR varCurrentValue = SELECTEDVALUE('Table'[Value],0)
VAR varAverage = [Average Value]
RETURN
    SWITCH(
        TRUE(),
        varCurrentValue > varAverage, "Green",
        varCurrentValue = varAverage, "Black",
        varCurrentValue < varAverage, "Red"
    )

1. 1. So if the current selected value (I used a slicer to select a value) is greater than the Average Value measure, return Green, if equal, black, if below, red. The average value measure is:

Average Value = 
CALCULATE(
    AVERAGE('Table'[Value]),
    REMOVEFILTERS('Table'[Category])
)

1. Then on the original card, select the label property and change the color from what is probably black to use the fx button conditional format:
   1. 

       

   2. Then select the Field Value setting, and select the measure you used -  Vs Average in my case.
   3. 

       

You can see my PBIX here if you want to play with it a bit. You can get rid of my green/red/black text and use hex codes as long as they are in the format "#000000" with the # sign to tweak those colors.
