> If demand arises for all of these context-specific interpolation methods, someone is bound to write a library for it. (Incidentally, I've written a tool to do colour management with a variety of colour spaces for exactly this reason; nothing really exists to do this on the web) There are indeed libraries for it, in various languages, which already demonstrates the need. In particular scientific visualization, and design systems, are two areas which have demonstrated the need for interpolation in perceptually-uniform colorspaces. > The most absolutely critical thing is that interpolation happens in a linear colour space whenever possible without causing issues for legacy. Of course there are many ways this might get implemented, but I'm strongly against the idea of interpolating colour in a colour space which is not a linear transformation from XYZ as a spec-level decision, especially by default. Since you mention XYZ, I guess that by linear you mean linear-light. Certainly that is one use case. There is also perceptual linearity, which is a different use case (you can't have both at the same time). I'm curious why you put perceptual uniformity in scare quotes. They have after all been in use for decades. -- GitHub Notification of comment by svgeesus Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/4647#issuecomment-665172537 using your GitHub account
