Code below finds a column with value A and pastes it in worksheet
output. How do I change the color of the cell when it pastes the
output?

Set wksDestination = Sheets("Output")
Set rngDestination = wksDestination.Range("A1")
Set wksToSearch = Sheets("Master Questions")
Set rngToSearch = wksToSearch.Columns("B")
Set rngFound = rngToSearch.Find(What:="A", _
LookIn:=xlFormulas, _
LookAt:=xlPart, _
MatchCase:=False)
If rngFound Is Nothing Then
MsgBox "Sorry. Not found"
Else
Set rngFoundAll = rngFound
strFirstAddress = rngFound.Address
Do
Set rngFoundAll = Union(rngFound, rngFoundAll)
Set rngFound = rngToSearch.FindNext(rngFound)
Loop Until rngFound.Address = strFirstAddress
rngFoundAll.Offset(0, -1).Copy rngDestination
