Opera address bar won't adequately change color scheme

Hello Opera community.

It is my first post ever.
So far I've always managed to solve the issues I had by searching solutions on the web but for my specific problem it looks more convenient to start a new discussion rather than go and search on the web.
Recently I decided to use one of the Windows Classic themes.
It turns out that my Opera browser will not change adequately the color layout so all the elements can be distinguished from one another. My particular problem is with the address bar which is black, so it is the text inside it and also the selection. So my entire address bar stays black no matter what I do there. Here are two screenshots. If I use the regular Windows Classic theme all seems right. Is it possible for Opera to have its own colors independently like Chrome does?
Anyway - How do I fix this problem? Keep in mind that I really want to stick with the Windows colors.

One from Opera and the another one from Chrome with the same Windows Classic theme.
