I do not think so. You may be able to simulate this by creating a button class the same size as the button on the dbo. Then modify the dropdown bitmap to change its color to whatever color you want [save the changed bmp to a different name]. Set the picture property of this button to the new bmp. Then when the cbo gets focus make this new button visible and send it to the front of the dbo and position it over the cbo's button.
