[csswg-drafts] [css-transitions][css-color] Animating currentColor

frivoal has just created a new issue for 
https://github.com/w3c/csswg-drafts:

== [css-transitions][css-color] Animating currentColor ==
The definition of [color 
interpolation](https://drafts.csswg.org/css-transitions/#animtype-color)
 isn't explicit about what should happen to `currentColor`. Given that
 it stays as a keyword at computed value time, one could think that it
 transition / animations between `currentColor` and other colors are 
meant to be discrete, but all browsers actually interpolate. This 
should be made explicit in the spec.

This could probably be done by adding the following sentence to the 
paragraph.

> Interpolating to or from `currentcolor` is possible. The  numerical 
value used for this purpose is the used value.
