It's only accessible through the settings (which you can only tell by
looking at the definition of panel.bwplot):

bwplot(voice.part ~ height, singer,
       panel = function(..., box.ratio) {
           panel.violin(..., col = "transparent",
                        varwidth = FALSE, box.ratio = box.ratio)
           panel.bwplot(..., fill = NULL, box.ratio = .1)
       },
       par.settings = list(box.rectangle = list(col = "darkgreen"),
                           box.umbrella = list(col = "darkgreen")))
