That is substantially quicker. Almost instantaneous, which is good enough
for me. Is there a reason that it didnt delete the column it also created?

Sub HideGrey()

Application.ScreenUpdating = False
Application.Calculation = xlCalculationManual

Set rngIsect = Application.Intersect(ActiveSheet. _
UsedRange, Range("A:A"))

Columns(2).Insert
For Each cell In rngIsect
If cell.Interior.ColorIndex = 15 Then 'Gray-25%
cell.Offset(0, 1).Value = 1
End If
Next
Rows(1).Insert
Range("B1").Value = "Temp"

Set rngColoured = Range("B1").Resize(Cells(Rows.Count,
"B").End(xlUp).Row)
rngColoured.AutoFilter field:=1, Criteria1:="1"
Set rngColoured = rngColoured.SpecialCells(xlCellTypeVisible)
rngColoured.AutoFilter
rngColoured.EntireRow.Hidden = True
Rows(1).Delete
'Columns(2).Delete

Application.ScreenUpdating = True
Application.Calculation = xlCalculationAutomatic

End Sub
