Color Identity: A Theme-Aware VS Code Extension - Tutorial (WIP)
Color Identity is a VS Code extension that gives each workspace a unique color derived from its folder name and your active theme. Inspired by the excellent Peacock extension, but I wanted more control over how colors are generated. Could we do theme-aware tints that adapt automatically rather than picking from a fixed palette? Plus, I wanted to learn how VS Code extensions actually work.
Currently, it just picks foundation colors based on dark/light theme, and then allows hue shift from there. I will be experimenting with it picking specific elements from your user-specified theme, and attempting to shift from within a color space that is aesthetically appropriate for the overall theme.
A 10-section tutorial is in progress, covering VS Code extension APIs, HSL color science, deterministic hashing, and a PNG encoder built from scratch. More to come once the tutorial is complete and the extension is hopefully published to the Marketplace.
