Please have a look at my screenshot:

As you can see there are two colors grey at the bottom and white in the upper part. I played a little bit with color settings but there is only an option for window backgroud. The gradient smooth transition I achieved by using (Bespin) style options. But this is not my desired effect. I wrote to Bespin author but this is not about Bespin. I wish there was an option in KDE color settings that could do that regardless of some specific theme configurations options. Actually Oxygen has only few options so there is not much that can be customized.

I wish I could also achieve similar effect as in second screenshot:

I mean this gradient of color on menu bar and column bars. Ideally I wish it was possible to pick an element of interface for example menu bar or other and choose option - gradient or even gradient transition between two colors.

I know that this last option might be rather difficult to achieve but at least consider the first one.
