Bsed on the Monokai pallete, but with the idea of keeping a neutral overall colour. I use Atom for a lot of graphics related work, and after trying to find themes without overall colour biases I gave up and decided to make my own. I still like a reasonably colourful syntax theme, because I suck at coding, and it helps me to see lots of colourful syntax highlighting.
Good catch. Let us know what about this package looks wrong to you, and we'll investigate right away.
