Harvey, thanks for the suggestion tried it but still can't it just as realistic as with combination of 3 or more colors like in gtk.css
But trying to add Aravisian's "invention" I get a pretty good result. Looking like this;
Storm - I use gnome and when using Alt Tab while switching for the available apps, this blue-ish color is visible. ( guess there are more places). Don't know if you also have this. But still I would like to find out where it's coming from.
