Ariake is an atom syntax theme inspired by Japanese traditional colors and the poetry composed 1000 years ago.
"有明の つれなく見えし 別れより 暁ばかり 憂きものはなし" - Mibu no Tadamine (壬生忠岑)
"Since I saw the moon in dawn when you said good-bye, My heart aches every time I see it again."
This theme is also a fork of One Dark Syntax.
The font used in the screenshot is Fira Mono.
There is also a matching UI theme.
