Feedback on my first product: a little open-source color system

Reasonable Colors is an open-source color system for building accessible, nice-looking color palettes.

The (maybe) cool idea here is that this color system is built programmatically in the LCH color space. Each of the color shades are pinned within certain relative luminance ranges, which lets me guarantee the minimum contrast between any two shades.

You can do some simple "shade math" to figure out the contrast. It's super easy to build accessible, high-contrast color combinations. Example: move two shades apart, minimum contrast 3:1.

Check it out, feedback welcome!

    Very nice! Can you add more shades? I’d love to see 10 per color group.
