Julia: ImplictPlots in a loop: setting colors

Question

How can I assign colors with implicit_plot?

using ImplicitPlots, Plots
v = [(x,y) -> (x+3)*(y^3-7)+18, (x,y) -> sin(y*exp(x)-1)]
p = plot()
for f in v 
    implicit_plot!(f; xlims = (-1, 3), ylims = (-1, 2), framestyle = :origin, lc = [:red, :blue])
end
p

I expected something along the lines of:

lc = [:red, :blue]
for (i, f) in enumerate (v)
    implicit_plot!(f; xlims = (-1, 3), ylims = (-1, 2), lc = lc[i])
end

How can I pass a gradient of blue colors for the second function? (I can pass lc = :blues but that makes the first line blue as well.)

Bonus question: Can I pass a vector or tuple to implicit_plot? I guess it's not supported.

Answer 1

Are you sure it does not work? I tried

lc = [:red, :blue]
for (i, f) in enumerate(v)
    implicit_plot!(f; xlims = (-1, 3), ylims = (-1, 2), lc = lc[i])
end

and I got

(You had an extra space in enumerate which maybe threw you off?)

Not sure about the tuple of functions.
