> is there a methodology to assign "dark" colors based on the existing "light" ones? Or should I do the design twice, one for the light and one for the dark mode version?

You can try inverting the colors used for the light theme to obtain a decent starting point for the dark theme design.

If you use SASS you can use `invert` for that, or `invert` from the CSS-in-JS library "polished"

For anyone curious how the inverse of a color is calculated, read this answer on StackExchange: https://graphicdesign.stackexchange.com/a/95100

Happy to hear you found it interesting!

> Do you have any idea if one could tackle this on a OS level and e.g. have a catalogue filesystem on a sub-section of my hard drive?

Unfortunately none of the available OSes support the many-to-many relationship between files and categories that I suggested (Symbolic links aren't sufficient[1]).

My hypothesis is that any sufficient solution will be much more complex than what I'm doing with Catalog, which means a lot harder to maintain.

Hi HN!

I'm very excited to be able to present Catalog to you here. In fact one of the reinforcements for my vision came from a post I read here a few months ago:

https://news.ycombinator.com/item?id=18858538

This app checks out almost all desirable features described in that post:

  - Free and open source
  - 100%-internet-independent.
  - It works on all the platforms: Windows, Mac and Linux
  - It uses SQLite as the store format of metadata, which makes it easy to read and modify programmatically.
  - A node can be either a filesystem resource: a file / folder, or a hierarchy building block: a category
  - All desirable metadata can be created by the user through categories
  - Search for files: by name OR by an ancestor category of the file

You're welcome to leave questions here, and I will try to address them as best as I can.
