Just to add:

If you put this in the userform's codemodule you can use:

Code:
sub snb()
  For j = 1 To 2
    Me("CommandButton" &j).backcolor = 12648447
  Next
end sub
it's the shorthand for
Code:
sub snb_longer()
  For j = 1 To 2
    controls("CommandButton" &j).backcolor = 12648447
  Next
end sub
or
Code:
sub snb_still_longer()
  For j = 1 To 2
    Me.controls("CommandButton" &j).backcolor = 12648447
  Next
end sub
