One way:

Public Sub Fill_in_red()
Dim i As Long
Dim dTemp As Double
With Sheets(1).Columns(1)
For i = .Cells(.Rows.Count, 1).End(xlUp).Row To 2 Step -1
dTemp = .Cells(i).Value - 1
Do Until dTemp <= .Cells(i - 1).Value
.Cells(i).EntireRow.Insert Shift:=xlShiftDown
.Cells(i).Value = dTemp
.Cells(i).Font.ColorIndex = 3
dTemp = dTemp - 1
Loop
Next i
End With
End Sub
