pastel
A tiny color workbench for the terminal. Convert color formats, generate palettes, and adjust colors in scripts.
Requirements
macOS on Apple Silicon (arm64) and a terminal. The binary declares a minimum of macOS 11.0; compatibility has not been tested. No separate Rust installation is required to use the prebuilt binary.
Quick start
Download the Boloop ZIP bundle for Mac Apple Silicon. First extract the ZIP and read the bundled notices, then extract its unchanged official tar.gz archive. Use pastel from Terminal or place it in a directory on your PATH. Keep the notices with your copy. Follow normal macOS security prompts; do not disable system protection.
pastel helps developers and designers work with colors from the command line. Convert between formats, mix colors, or generate distinct colors for a chart. Commands can be chained together in a shell.
Best for: design-system experiments, quick color conversions, and repeatable color tasks.
