Since we want to expose "used values” and “active values" by CSS OM - why not let currentColor always get the same color that a “active value” property or function would return? I mean we should not differ between currentColor with “sanitized ‘color’” and another one. Just always use the  “sanitized ‘color’” for currentColor.

You don’t need to feel attacked. I was barely saying that the behavior of currentColor changed anyway and probably isn’t compatible to implementations anymore. I don’t think calling currentColor to be “broken” is particularly wrong here. And at least I didn’t say it was a “silly" idea to change the behavior. So please lets get back to solid grounds where this discussion is supposed to be.

Lets come back to the topic. You said you don’t want to change the behavior of currentColor to avoid breaking things. On the other hand you are fine to change the behavior of currentColor for feFlood, feLighting and other situations where necessary. I would like to avoid the inconsistency here since that is confusing.

Greetings,
Dirk
