[BUG] Colors are not assigned to pie chart properly

[bvilmann]

Details

Colors are not assigned to pie chart properly.

This:

pie(rand(3),
    color=[:blue :green :red]
    )

Plots this:

Regarding a closed issue, I am using the correct syntax for assigning colors.

Taken into account that I am new to Julia and Plots, I looked in the source and found that the recipe does not handle any input colors:

@recipe function f(::Type{Val{:pie}}, x, y, z)
    framestyle --> :none
    aspect_ratio --> true
    s = sum(y)
    θ = 0
    for i in eachindex(y)
        θ_new = θ + 2π * y[i] / s
        coords = [(0.0, 0.0); partialcircle(θ, θ_new, 50)]
        @series begin
            seriestype := :shape
            label --> string(x[i])
            x := first.(coords)
            y := last.(coords)
        end
        θ = θ_new
    end
end
@deps pie shape

Is this part of the problem or lies this elsewhere?

I would happily implement changes but I need some supervision for this.

It should now work with a vector of colors like [:red, :green, :blue].

Passing a row vector [:red :green :blue] still makes the pie entirely red but I think that's expected since each column corresponds to a series and a pie plot is only one series.
