A syntax theme based on @simurai's Duotone Dark Syntax.
Blessed Dark uses only 2 hues and 7 shades in total. It tones down less important parts (like punctuation and brackets) and highlights only the important ones. This leads to a more calm color scheme, but still lets you find the stuff you're looking for.
More optimization to come..
ps. The font in the screenshot is
Fira Mono. You can download it from https://github.com/mozilla/Fira
Good catch. Let us know what about this package looks wrong to you, and we'll investigate right away.
