I’m having this issue while doing this visualization. The color of some markers are supposed to be red instead of black. Could you please help me how to fix this?

Here is my code

```julia
using Plots
using Random 

n = 5

mypoint = (rand(1:10, n), rand(1:10, n))
mybool = []

push!(mybool, BitVector(undef, n))
push!(mybool, bitrand(n))

anim = @animate for v in mybool
    scatter(mypoint, markersize=10, c = map(x -> x ? :red : :green, v))
end

gif(anim, "point.gif", fps=1)

```

I can reproduce this, and it’s _weird_.

Just to get the obvious things out of the way, you can use `falses` to initialize a zeroful BitArray, so

```julia
mybool = (falses(n), bitrand(n))

```

The problem still appears here.

```julia
colors = (fill(:green, n), rand([:red, :green], n))
anim = @animate for v in colors
     scatter(mypoint, markersize=10, c = v)
end

```

shows the same issue.

```julia-auto
colors = (rand([:red, :green],n), rand([:red, :green], n))

```

does not, unless the first vector is all the same color.

```julia-auto
colors = (rand([:red, :green],n), rand([:red, :green, :blue], n))

```

makes the points in the second plot which should be blue gray.

### Conclusion

The first frame in an animation sets the gamut, and any other colors in subsequent plots are replaced by gray. I would have suggested a bug report to `Plots.jl`, but I see you already have.

Could this be related to the implementation [of this idea](https://github.com/JuliaPlots/Plots.jl/issues/423) in `ffmpeg_exe` with the new setting: `"palettegen=stats_mode=diff"` ?
