Band plot ignores alpha keyword

[TomRottier]

    f = Figure()
    ax1 = Axis(f[1, 1], title="alpha = 0.5")
    ax2 = Axis(f[1, 2], title="color = (:red, 0.5)")
    xs = 1:10
    lower, upper = fill(-1.0, 10), fill(1.0, 10)
    band!(ax1, xs, lower, upper, color=:red, alpha=0.5)
    band!(ax2, xs, lower, upper, color=(:red, 0.5))

I had a similar experience. Thanks for the workaround of putting color and alpha together as a tuple

I also had this issue. Thanks for the workaround!

We should still fix this - people specifying color as e.g. Cycled won't have the option of a color tuple

Would just need an alpha here: https://github.com/MakieOrg/Makie.jl/blob/master/src/basic_recipes/band.jl#L14 And then needs to be added to attr here: https://github.com/MakieOrg/Makie.jl/blob/master/src/basic_recipes/band.jl#L56

Works for me in GLMakie and WGLMakie on master. Doesn't work in CairoMakie
