[Feature Request] consistent perceptual luminance

[parkersweb]

First - amazing work - looks great!

One enhancement I'd love to see - as colours are added to the collection is there any way the the tints could all be matched to the same perceptual luminance - possibly using HSLuv (https://www.hsluv.org/)?

There's a good reason for doing this - design systems like Shopify Polaris (https://polaris.shopify.com/design/colors/palettes-and-roles) use HSLuv to ensure that the relationship between tints of different colours create the same contrast ratio for accessibility. The upshot of this is that you can put magenta-14 against pink/gray/yellow/ -7 and know it'll meet minimum contrast requirements.
