Generate terminal color schemes.
Xiwal is a tool that generates color schemes from colors. The colors can either be specified directly or extracted from an image. It is massively inspired by [pywal](https://github.com/dylanaraps/pywal), but it also has some important differences: - Xiwal focusses on terminal color schemes. There is no integration with gtk, i3, polybar, etc. - The colors are reordered to match the traditional "red, green, yellow, blue, purple, cyan" structure as close as possible. - All generated color schemes use the same CIE Lab lightness levels. They are based on my personal experience/taste. - Since red and green are important signal colors (e.g. in diffs), their saturation is increased.
