Color for front door

My son and his wife live in a development of houses w/ maybe 4 diff designs. The colors are similar but not exactly alike. We were talking about painting the front door (currently black) to make their home a bit diff from their neighbors. To say nothing of the fact I get confused where they live. They are in Bend, Oregon. The house is 1 story w/ primary color a grayish green, light and muted. A muted forest green is the main accent color. Shutters and doors black. Apple green door? straight orange, not burnt orange? Maybe change the shutters too but not necessarily the door color. Oh you guys w/ eye for color, where are you?
