Stardust is a colorful yet subtle syntax theme for Atom. Stardust's palette is a highly modified version of Github's syntax on a dark background.
I highly suggest you to use
Source Code Pro as the editor font,
16px of font-size and setting
3 as the editor line height. Works best with
Nucleus Dark UI theme.
Good catch. Let us know what about this package looks wrong to you, and we'll investigate right away.
