Reset color cycle with RecipesBase

Say I define a struct Example like:

struct Example
    fields
end
example = Example([rand(3), rand(3), rand(3)])

Using RecipesBase, I can define a plot recipe that allows me to plot each component of such a struct:

using RecipesBase
@recipe function f(example::Example)
    N = length(example.fields)
    for n in 1:N
        @series example.fields[n]
    end
end

When I run plot(example), each component example[n] is plotted with a different colour, as expected:

using Plots
plot(example)

example

How can I change the above recipe such that it resets the color cycle at every iteration of the for loop? The application I have in mind is for structs (of arrays) of more complex plottable objects.
