Consider using the new GUI instead.

1. pip install prev_gen
2. Open up the wiki to see how everything works
3. Create a file based on instructions (or just edit the python, yaml, json, or toml examples)

4. # in a python file
   from prev_gen import Previewer
   palette = [...]
   Previewer(palette)

   or use the cli tool prev_gen for conversions with no code

If you're using an older version of the library, pin the version to prev_gen<6.0.0 or upgrade by following the guide.

Inspired by the great Gruvbox theme, where even the preview is impressive
And so, below is the Gruvbox palette preview recreated with this app (click for selectable text)
