What is openswatch?

OpenSwatch is a free, open-source color palette designed for use in websites and web apps. It gives you a ready-made set of colors that are meant to be practical and flexible, so you don't have to start from scratch when picking a color scheme for a project. The system includes 20 different colors, each broken into 12 shades (from light to dark), plus a 13-shade neutral scale covering grays. The colors are built using a relatively new color space called OKLCH, which is designed to match how humans actually perceive color. This means the steps between shades look more visually even than in older color systems. Because the shades are calculated consistently, you can make small adjustments, like shifting a color slightly lighter or darker, and get predictable results without manual tweaking. This would be useful for web designers, frontend developers, or anyone building a product interface who wants a polished color system without designing one from the ground up. For example, if you're building a dashboard and need a blue with enough shades for backgrounds, borders, hover states, and text, the palette gives you those steps ready to go. The neutral scale handles the grays you'd use for text, dividers, and muted backgrounds. The project is built entirely in CSS, so it integrates with modern web workflows without extra dependencies. Beyond that, the README doesn't go into much detail about specifics like how to install it, how to customize the colors, or what CSS variables it exposes, but it links to a website for more information.
