Color theme

[arcticicestudio]

Implement the main color theme file.
It should be implemented as 16 colorspace theme with support for the terminal- and GUI mode.

Colorspace design decision

Nord Vim is not designed for the 256 colorspace to keep it faithful to the Nord design guideline. The 256 colorspace limits the possibility to create the same ambient and does not provide the necessary color shades.

Language

Nord Vim should implement optimized styles to achieve a consistent and uniform coloring across languages. This includes support for third-party language plugins for more highlighting groups.

Colors

The order of the colors must reflect the ANSI Escape Code Colors for foreground and background.

Foreground: nord4
