Examples

plot(x=rand(12), y=rand(12), color=repeat(["a","b","c"], outer=[4]),
     Scale.color_discrete_manual("red","purple","green"))

D = by(dataset("datasets","HairEyeColor"), [:Eye,:Sex], d->sum(d[:Freq]))
 rename!(D, :x1, :Frequency)
# Is there a hazel color?
palette = ["blue","brown","green","tan"]

pa= plot(D, x=:Sex, y=:Frequency, color=:Eye, Geom.bar(position=:stack),
    Scale.color_discrete_manual(palette...)
)
pb= plot(D, x=:Sex, y=:Frequency, color=:Eye, Geom.bar(position=:stack),
    Scale.color_discrete_manual(palette[4:-1:1]..., order=[4,3,2,1])
)
hstack(pa, pb)
