Sorry for my late answer for the following. I somehow must have overread=20

Swapping (or inverting as you call it) foreground and background colors=20
does not work for accessibility reasons. There are people who can only=20
read light text on a dark background. Even larger bright areas can dazzle=20
them.

As you never know why someone chose a particular combination of colors it=20
is best to avoid using foreground colors for a background and vice versa.

Using a blending algorithm for generating additional background colors=20
sounds better, but I need to give some thoughts to whether it is a safe=20
solution (or whether there may be problems, too, in certain very special=20
situations).

As to my understanding kde-core-devel is more suited for the technical=20
aspect of the topic I would like to move the discussion about which color=20
roles are exactly needed to the mailing list of the HCI workgroup=20
(kde-hci@kde.org).
