:zap: New colorschemes based on Julia colors.

[davibarreira]

@cormullion we meet again! :grin:

I didn't see any color schemes based on Julia's colors. So here is a PR with a proposal of color schemes based on Juila. If you find the color schemes redundant, feel free to reject the PR.

Hi Davi. This looks cool, thanks!

You'll need to remove the stray semicolons.

What's the thinking behind the :jyellow and :jgray?

The yellow and gray are just extra colors to the regular Julia color scheme that I felt complemented the original palette. I mean, having only 4 colors might be too little for some plots, and I felt that the yellow and the gray matched the original Julia colors.

But I'll remove them. I think it's better to stick only to the originals.

About the color gradations (jblue, jred, etc). They are a variation in 10% of the colors.

Forgot to add the legacy colors. These are the colors from the original logo :)

[cormullion]

That's great! Thanks so much! :)

Loose ends:

• Updating the docs usually is just a question of adding another couple of lines to the MD.

• CHANGLOG needs updating at some point
