If someone pasted text in a data validation dropdown and it doesn't match with the Data validation list, I'm highlighting the cell by using a red font color range..Font.Color = vbRed
I'm using the below UDF as an Excel formula to find out the font color of the cell, but this UDF is not calling until I select the cell, go to formula bar and hit enter.
Function GetColorText(pRange As Range) As Integer
Application.Volatile
If IsEmpty(pRange) Then Exit Function
Dim xOut As Integer
xOut = pRange.Font.ColorIndex
GetColorText = xOut
End Function
