How do I import all the color schemes from ColorSchemes in one go?

Thanks.

P.S.

This code used to work before.

```julia
using Plots, Random
cs = collect(keys(colorschemes))
cp = first(Random.shuffle!(cs))
plot(x, y, palette = cp) # some x, y

```

Not anymore. I get this error:

```julia
ERROR: There is no gradient named isoluminant_cm_70_c39_n256 . Use cgradients() to get a list of gradients in the current color library, clibraries() to get a list of available color libraries

```

Seems i need to explicitly import every scheme before using? Strange though, it used to work before. Any help is much appreciated.

Hi!  
Importing `ColorSchemes` seems to do the trick

```julia
using Plots, Random, ColorSchemes

```

It’s true that you can use colorschemes from ColorSchemes.jl without `import`ing or `using` it - because I think it’s `used` and `reexport`ed by PlotUtils. So this works in a session that hasn’t `import`ed or `use`d ColorSchemes:

But this won’t give you access to other things from inside ColorSchemes.jl, such as the list of colorschemes, or the `findcolorscheme()` wildcard search function. For that, you would need to do a `using` or `import`…

I think that’s how it works… (Not sure really… :))

Still no cigar.

```julia
using Random, Plots, ColorSchemes
plot(randn(50, 5), palette = :vermeer)

ERROR: There is no gradient named vermeer . Use cgradients() to get a list of gradients in the current color library, clibraries() to get a list of available color libraries

```

Works for me. (Plots v1.10.5) (Although not the most realistic Vermeer I’ve seen.)

and as before you don’t need the `using ... ColorSchemes` for this to work, since PlotUtils does it for you. (Although you won’t be able to do `collect(keys(colorschemes))` until you use or import it.)

It works now. Turns out installing JuliaDB broke Plots. I removed JuliaDB and it works again. Strange.

Thank you!

Cool. It’s probably the same as [https://github.com/JuliaData/JuliaDB.jl/issues/374](https://github.com/JuliaData/JuliaDB.jl/issues/374), JuliaDB holding Plots back for some reason…

Aha! Thanks for the reference Cormullion.
