First of all hello to every one. I'm not a developer, a designer and if this were not enough I'm not a good english speaker, I will try to explain myself the best I can.

One of my favorite plasma themes always have been Tibanna. It's great because plasma follows the colors of the windows/applications and the overall desktop gains uniformity and coherence: just like the old classic gtk2 desktops (xfce, gnome2) with plain non transparent panels, when I switch to xfce4 and then come back to KDE4 I miss this. Everything is more simple. From my knowledge, as far as I know the only themes supporting this feature are Tibanna and Aya. One user can mix different plasma themes from settings "personalize desktop theme" and mix tibanna with other themes but in my opinion sometimes it doesn't fit very well and it isn't very obvious to most users.

One example to view what I'm trying to pose is selecting a dark window theme and a bright plasma theme. Because the window theme is dark you must choose an icon theme with light colors otherwise you can't see them (well, with oxygen icons this doesn't happen but with more monochrome icons yes). What happens then is whilst window icons are light against dark background the panel icons are light against light background making them almost invisible so you must change the plasma theme and find something that fits well with window colors. With Tibanna like plasma the panel color fits perfect with icons and windows automatically.

I'm my humble opinion this kind of issue is one of the reasons why are much more less good/complete themes/icon themes in KDE compared to the vast amount of GTK ones available: It's very hard to achieve a consistent look between all components of the desktop environment (and the GTK integration always has been a nightmare, but this is not a QT fault).

Why don't implement something like Tibanna color scheme in the default plasma theme? Is svg format problematic with this and have limitations? Why there are no people making plasma themes with this feature?

What do the design group think about this? It's a good or bad idea? Thanks.

Andrew may correct me if I'm wrong, but as far as I know the idea for the future of the Breeze Plasma theme is indeed to respect the user-specified color scheme.
