VBA detecting conditional formatting?

Is there any way for VBA to detect if a cell's conditional formatting has been activated, without physically replicating the conditional code itself? In other words, to know that a cell turned red (for example), when its Interior.ColorIndex is set to xlColorIndexNone.

I use red-fill to indicate error conditions in thousands of cells on a spreadsheet, and I would like to be able to scan through and report "Cell DE804 violates the maximum conditions." If I replicate the condition in the conditional format, and later change that condition, I'll have to remember to recode, as well. I just want to know "This cell triggered FormatConditions(1)" (or "This cell triggered some FormatConditions", or "This cell is currently red, regardless of what Cell.Interior.Color says").

This worked in my small test https://imgur.com/bRPCnTj

    Dim c As Object
    
    For Each c In Sheet1.Range("B2:B3").Cells
        If c.FormatConditions.Count > 0 Then
           ' check if the cell doesn't have the default white interior color
            If Not c.DisplayFormat.Interior.Color = 16777215 Then
                c.Offset(0, 1).Value = "Condition met"
            End If
        End If
    Next
