Overlays themselves are defined by \defineoverlay. \defineoverlay[myoverlay][all kind of tex things] \setsomethingup[background=myoverlay] When more overlays are defined (or color is also used): \setupsomething[background={color,myoverlay,hisoverlay,heroverlay}] When the overlay code is executed, one can use the macros \overlaywidth, \overlayheight, \overlaycolor.
