A colleague suggested using PaneSelector to hide the popup menu when
it's not in use:

Manipulate[
Graphics[{If[color, c, Black], Circle[{0, 0}, 1]},
 ImageSize -> {400, 400}],
{{color, True, "color on"}, {True, False}},
Item[
 PaneSelector[
  {True -> Row[{
      "select color",
      PopupMenu[
       Dynamic@c, {Red -> "red", Blue -> "blue", Green -> "green"}]
      }, Spacer[3]],
   False -> ""
   }, Dynamic@color
  ]
 ],
{{c, Red}, {Red, Blue, Green}, ControlType -> None},
ControlPlacement -> Left]
