[WinAPI] TextOut() color and window background color do not match, how to set the same color for both of them?

Question

C++ / C#

The problem is that text is displayed in the window and its background does not match the background of the window.
It looks like this:

The color of the window itself looks like this:

...
wc.hbrBackground = (HBRUSH)(COLOR_WINDOW);
...

I change the color of the text using this function:
SetBkColor(hdc, ...);
The second parameter is COLORREF , it can be obtained using the RGB() macro , but what is COLOR_WINDOW RGB ?
Tried to get it like this:

SetBkColor(hdc, RGB(
  GetRValue(GetSysColor(COLOR_WINDOW)),
  GetGValue(GetSysColor(COLOR_WINDOW)),
  GetBValue(GetSysColor(COLOR_WINDOW))
  ));

But the text remains completely white.
Of course, using Photoshop, I found out that this is 240;240;240, but that's not good enough.
What to do?
PS
These functions

GetRValue(GetSysColor(COLOR_WINDOW)),
GetGValue(GetSysColor(COLOR_WINDOW)),
GetBValue(GetSysColor(COLOR_WINDOW))

They output 255;255;255, and if you use COLOR_WINDOW - 1(which corresponds to COLOR_MENU) , then the answer is correct(240;240;240), why is this happening?

Answer 1

SetBkMode(hdc, TRANSPARENT) ?
