Generates consistent themes for 20 tools from one palette contract instead of manual ports.

Strengths

•Semantic color mapping ensures errors look identical across editor and terminal.

Weaknesses

•Theme preference is subjective, limiting broad adoption beyond personal taste.
•Maintaining 20 tool integrations is high overhead for a solo maintainer.

Post Description

A few months back I wanted a fresh start with my terminal after 10+ years with the same prompt design and . I made an oh-my-posh prompt with colors I liked, called it Slatewave, and then just kept going.

VS Code didn’t match so I ported it. Then tmux, Obsidian, Alfred, Ghostty. After that I started picking off tools other people use. Raycast first since a bunch of my coworkers use it. Then other terminals like Alacritty, iTerm2, WezTerm, Windows Terminal. Starship and Logseq too since I’d used them previously. At some point I realized I had gone way further than I meant to. Scope creep was real.

It ended up as around 20 themes all built from the same palette. Mostly slate backgrounds, teal as the base color, and the same accents meaning the same thing everywhere. Rose for errors and git-dirty, purple for storage and git-ahead, stuff like that. All WTFPL.

https://getslatewave.com has live previews so you can flip between an editor, a terminal, and a notes app and see how the colors line up.

I would love feedback, especially on tools I missed or anything in the palette that feels off.
