In [Properties & Values](https://drafts.css-houdini.org/css-properties-values-api-1/#calculation-of-computed-values), nothing describes how they are...

I have lately been using `@property` a fair bit, and in nearly every real case, I had wished [`initial-value`](https://drafts.css-houdini.org/css-properties-values-api-1/#initial-value-descriptor) could have just been automatically set based on my `syntax`. There...

[css-typed-om] CSSColor should use indexed properties, not .channels
