I understand the problem when we cannot modify Color, but it is not such a common case + probably in the future we will be able to use extension interfaces.

External interfaces?

@Andreas Sinz I think he means stuff like:

extension Foo {
    fun bar() {}

[Andreas Sinz]

is this feature documented anywhere?

No, it's in the proposal stage, hence the wording "possibly in the future" :P
