Group Selected Worksheets By Color

I would like to do is to sort only selected sheets. Can someone give me this additional code that can be incorporated in the code below. (If I just select the sheets I want sorted and run the code below, it sorts all worksheets irrespective of whether it is active or not).

Sub SortWorksheets()
Dim N As Integer
Dim M As Integer
Dim FirstWSToSort As Integer
Dim LastWSToSort As Integer
Dim SortDescending As Boolean
SortDescending = False
If ActiveWindow.SelectedSheets.Count = 1 Then
FirstWSToSort = 1
LastWSToSort = Worksheets.Count
Else
With ActiveWindow.SelectedSheets
For N = 2 To .Count ................
