@kthyng: Nice colormaps... how would you feel about contributing to the available colormaps for visualization in Julia?

Strongly pro! I'm not familiar with Julia syntax though. Happy to
facilitate if someone knows and can do it more quickly.

Excellent. 🎉 It's up to you... if you were to give us a list of colors for each map, it wouldn't be too hard for us to add it. I'd set you as the author of the commit so that you get credit for it, and I'd link to your paper at the top of the file. Let me know.

Cool — the rgb values are in text files here:

These are really nice. Thanks for letting me contribute them on your behalf @kthyng!

using Plots; pyplot()
cmaps = [:algae,:amp,:balance,:curl,:deep,:delta,:dense,:gray,:haline,:ice,:matter,:oxy,:phase,:solar,:speed,:tempo,:thermal,:turbid]
z = (1:10)*(1:20)'
plot([heatmap(z,fc=cm,leg=false,title=cm,ticks=nothing) for cm=cmaps]..., size=(1000,1000))

@pkofod do these inspire you to make any new themes?

[tbreloff]

Also... isn't it about time you ditch python and switch to julia? ;)

@tbreloff Nice work, Tom! I see there's no shortage of color fans using Julia!

using Plots
using ColorSchemes
pyplot()
z = (1:10)*(1:20)'
map(cs -> PlotUtils.register_gradient_colors(Symbol(cs), loadcolorscheme(cs)), list());
cschemes = keys(PlotUtils._gradients)
plot([heatmap(z,fc=cm,leg=false,title=cm,ticks=nothing, titlefont = font(8)) for cm=cschemes]..., size=(1000,1000))

The only interesting thing about ColorSchemes is that you can extract them from existing images. If there's anything useful there, help yourself! :)

Edit: Fixed the font size for the labels...

[tbreloff]

Very cool! It might be nice to have a few methods to easily load external
color packages without adding the dependecies

(PS: Sorry about the too-large labels...)

Cool! And I've heard only good things about Julia, indeed.
