Oh yeah! This theme is still under development. BUT, I've done it with love for you! That's right! FOR YOU
Now, atention: This project was forked from the amazing Atom Material UI Theme, then any similarity is not mere coincidence
Fire up a console and type:
apm install tapioca-ui
Or, inside Atom's settings select Install and then search for this package.
Atom Material UI supports different accent colors. To change it, go to Settings > Themes and click the cog icon next to the theme selector.
You'll find the color picker there.
Here's the obligatory screenshot.
