Iosvkem is a colourscheme based on the default dark theme for Adobe Brackets.
It got its name from the Iosevka
typeface, as its website is where I first noticed the colourscheme.
It supports both true colours and 256 colours terminal emulators. There is some limited support for monochrome terminals, which I can only hope will be useful to our children as they hide from the radioactive fallout in underground bunkers.
I have no interest in supporting 3rd party plugins, or alternative syntax files unless the default files that ship with vim are broken or inferior to the point of being useless.
I have had to rewire a few things for markdown, rst and diffs to work properly, but the rest of the theme respects the conventions built-in within vim. Switching from Iosvkem to another theme shouldn't break anything else.
Iosvkem was made using colortemplate. It's good. Try it.
