I was searching how to get system theme color. I found GetSysColor and GetSysColorBrush. Then I tested it with something like that:

```cpp
    cout << GetSysColorBrush(COLOR_HIGHLIGHT) << endl; //checking the value if it's changing when 
                                                                   //changing system color

    WNDCLASSW wc = {0};
    wc.hbrBackground = GetSysColorBrush(COLOR_HIGHLIGHT);
    wc.hCursor = LoadCursorA(NULL, IDC_ARROW);
    wc.hInstance = hInst;
    wc.lpfnWndProc = WindowProc;
    wc.lpszClassName = L"WindowClass";

    if(!RegisterClassW(&wc)) return -1;

    CreateWindowW(L"WindowClass", L"Window Name", WS_VISIBLE | WS_POPUP, 0, 0, windowWidth - 500, 
                                           windowHeight - 500, NULL, NULL, NULL, NULL);

```

I thought it works, because I had default blue theme and the window was blue (exactly same color), then i changed my theme to green but window was still blue (after restarting program obviously).

And now my question: **Is it possible to get current system theme color?**
