This code below of your is working wonders!! Very pleased with it in the early testing stages. Looks like it will really do the trick.

I am calling it from the my code that sets the Day and the Desk, I assume that is how you intended it to be used.

Questions for my own enlightenment(in order as the appear in the code):

1. This returns C because the cell address is $C$n, second char = C ?
If Mid(myRng.Address, 2, 1) = "C" Then

2. With 0 it did nothing but works well with -4142. No problem with that is there?
If rngC.Interior.ColorIndex = -4142 Then
'If rngC.Interior.ColorIndex = 0 Then

3. You can see the lower half of the code is commented out and it still works perfect. Was that a typo of sort or what?
