We've integrated our new color scale editor into our existing color scale generator. We've deprecated the page at shadow-tint-scale and consolidated the functionality into /color-scale. Existing shadow-tint URLs will redirect to /color-scale.
We've also updated the component to allow for constraining color inputs to pull from existing theme values as well as cycle through generated scales.
As with existing components, you can save a scale by upvoting or liking in the actions panel.
