The whole [issue of additive CSS](https://github.com/w3c/csswg-drafts/issues/1594), opened in 2017, is still being discussed. Additive animation makes sense for things like lengths but seems less valuable for color (I guess, in RGB spaces, adding or subtracting a constant offset on a per-component basis is a way to crudely increase or decrease the lightness, if you don't care about the hue changing wildly). Good question about what to do about hue, if additive animation takes place in a polar space. I feel I need to better understand what the use cases are for additive animation of colors, to understand how that should behave. Note that [premultiplication in polar spaces](https://w3c.github.io/csswg-drafts/css-color-4/#interpolation-alpha) is already defined, at least. -- GitHub Notification of comment by svgeesus Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/7793#issuecomment-1267101435 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
