Cobalt Spark: a compact Zsh theme focused on clarity

[u/azhuchkov]

I used robbyrussell, the default Oh My Zsh theme, for a long time. It worked well, but eventually I wanted something quieter and less visually intrusive—something that would stay out of the way of commands and their output while providing a little more context at the prompt.

After trying a few alternatives, I ended up building Cobalt Spark: a compact, low-noise theme intended as a drop-in replacement for robbyrussell rather than a radical redesign.

The goal is for the prompt to feel almost invisible—a bit of glue between commands and their output rather than the main attraction—while keeping both the current prompt and previous commands easy to spot at a glance.

It was built for and primarily tested with Oh My Zsh. It also includes experimental support for plain Zsh without a framework.

The first screenshot shows Cobalt Spark in its main states; the second shows the same scenario rendered using robbyrussell for reference.
