This is awesome! As a new maintainer of BenchmarkTools I'm enthusiastic about this
Would it perhaps look better with arcs of the same width, ordered blue < green < red < violet? I'm colorblind so don't take my word for it

Hi @gdalle ! A necrocomment for sure... :) The code should work fine on today's Julia. The color sequence for the lower three bands is set in line 22, and it may or may not look better in a different order - who knows? :) The colour gradient of the top band is set in line 15... The thickness of top band is set in line 18 (band/2), and I made it different width because it clashed with the red a bit otherwise. Feel free to adjust it to your heart's content - have fun!

If you want alternatives or further changes, just let me know...

I love a good necrocomment :) sorry for the ping, I'll experiment a bit on my side

No, I love a good ping. Shout if you want anything - I'll get to a real computer later ... !

Yes, the gradients are linear or radial, so a curved one might be tricker. Obviously you could do it by drawing small sections:

using Luxor, Colors
@draw begin
    δ = π/220
    starthue = 30
    for (n, θ) in enumerate(deg2rad(220): δ : deg2rad(320))
        sethue(HSB(starthue + n, 0.9, 0.8))
        sector(O, 150, 200, θ, θ + δ, :fillstroke)
    end 
end

or you'd have to use meshes ...

Thanks, on second thought I think it's a bit overkill for our use case. I already like the way this looks: JuliaCI/BenchmarkTools.jl#316

Cool stuff!
