Not ideal, but I do this:
using Gadfly, RDatasets
theme = Theme(
minor_label_color=color("#aaaaaa"),
major_label_color=color("#dcdccc"),
point_label_color=color("#dcdccc"),
key_title_color=color("#ffffcc"),
key_label_color=color("#dcdccc"))
plot(dataset("car", "SLID"), x="Wages", color="Language", Geom.histogram,
theme)
