  1. I feel like some context is missing from the article. Where does the keyword `from` come from? This doesn’t seem to work, and I can’t find any reference to it in the CSS specs.

    `–color: hsl(from var(–color) h calc(s – 10%) l);`

  2. I’m pretty sure it has only been implemented on Safari as of right now. I’m not sure of the progress being made on Chrome, FireFox, etc. This appears to come from the Color Level 5 spec which is still in early development. Chrome has just released Color Level 4 and Color-Mix() from the Level 5 spec on Chrome 111, but I cannot find any status update on the remainder of Color Level 5. It appears they are still in the very early stages of development and implementation. I haven’t found any mentions of this on the roadmaps for at least the next few releases of Chrome.

  3. Samual, great article! Thanks.

    I was just about to say the same thing as @EdCharbeneau pointed out. Checking MDN first, I couldn’t find anything about relative colors.

    With Adam’s comment I then found high level browser status for color module 5 on w3.org https://www.w3.org/TR/css-color-5/

    and then the more specific tests for relative-color:

    I think it would be good if it were mentioned up in the article section as long as browser support is so sparse.
