The palette doesn't seem perceptually uniform, i.e. the contrast ratios of each tint vs. white/black aren't the same across all colors. Did your try analysing the palette in https://huetone.ardov.me/ ?
I've analyzed the palette with my own tool, a11y-contrast[1], and indeed the luminance is not uniform. I wrote [2] about why this might be a desired property of a color palette.
Nope, I just did what felt good. Does the huetone tool support OKLCH? I didn't see a toggle for it.
You have to convert your OKLCH colors to RGB hex codes before you can import them to Huetone, and that's little bit annoying, but worthwhile. I wouldn't use any palette that isn't perceptually uniform anymore. Being able to switch e.g. red-400 to blue-400 and to retain same contrasts is very valuable.
