Plots.jl / GR: Specify colors for multiple series

I want to plot two series and I want to specify a color for each of them. How do I do this? This code:

plot([1:10, 2:11], markershape=:circle, color=[:red, :blue])

Does not do what I want:

Series are generally treated column-by-column:

plot([1:10 2:11], markershape=:circle, color=[:red :blue])

Mind = blown. It makes so much sense once you know it! Thanks!
