A low contrast syntax theme with a deep sea feel. There is no pure red, orange, and yellow, while the rest of the palette hints heavily towards the blue side of the spectrum.
Seabed comes in two distinct packages, a dark and a 'lighter' dark version (see further info below). This is the dark one.
The font is Iosevka term.
The UI is my experimental fork of the default One Dark.
seabed-dark-syntax in Settings > Install > Themes. Or install it directly using the command:
apm install seabed-dark-syntax

Seabed 'lighter' dark version: https://atom.io/themes/seabed-syntax
Good catch. Let us know what about this package looks wrong to you, and we'll investigate right away.
