How to return the colour of a cell

Hello

I have a bit of code that works fine - as follows:

*************************************************
Sheet1.Unprotect
    For Each rngCell In Sheet1.Range("listing")
            If Not rngCell.Locked And Not IsEmpty(rngCell.Value) Then
            rngCell.Locked = True
            rngCell.Interior.Color = RGB(200, 200, 200)
            intN = intN + 1
        End If
    Next rngCell
    Sheet1.Protect
***************************************************

This looks in a range and finds any unlocked cells with content and then locks and colours them.

In another routine, I would like to do a similar thing, but instead of looking for the locked status I would like to look for a specific cell colour (or NOT a specific cell colour).

Is there a statement that would do that please?

Regards

Richard
