Cosmical Logo

Cosmical

An Obsidian theme created to enhance the note taking experience. It balances color use inspired by coding editors and a neutral background to keep things balanced

Important: Cosmical ignores the user accent color and uses it's own color-scheme, you need to install the "Style Settings" community plugin in order to select a diferent color-scheme.

Theme

My main goal with Cosmical is to make Obsidian look more atractive while maintaining focus and not adding distractions.

Two main features:

  • A neutral background inspired by Gnome
  • Rich accents and vibrant colors inspired by coding editors

The plugin Style Settings is needed to pick a different subtheme.

  • Control sidebar toggle button visibility
  • Improved multi-select list UX
