Get Mica or Mica Alt color in Windows 11

[electryon]

Hi, thank you in advance for any reply.

Is there any way to retrieve the Mica colors Windows 11 adds?

I mean get them as hex color values.

Maybe with _WinAPI_GetSysColor, dwmapi, DwmGetWindowAttribute?

Somehow? I wouldn't want to make a screenshot of windows 11 explorer and get it with a scrren color picker from its titlebar.

There must be a better way.

Thank you again in advance for any reply.

From what I've found you can gey it with DWMWA_SYSTEMBACKDROP_TYPE with DwmGetWindowAttribute

DWMWA_SYSTEMBACKDROP_TYPE
Use with DwmGetWindowAttribute or DwmSetWindowAttribute. Retrieves or specifies the system-drawn backdrop material of a window, including behind the non-client area. The pvAttribute parameter points to a value of type DWM_SYSTEMBACKDROP_TYPE.

If someone knows more about how to call dwmapi with that attribute, please let me know.

Thank you again in advance for any reply.

Global Const $DWMWA_SYSTEMBACKDROP_TYPE = 38

$tResult = DllStructCreate('int DWM_SYSTEMBACKDROP_TYPE;')
$hWin = WinGetHandle('[ACTIVE]')    ; Change with your window handle
DllCall('Dwmapi.dll', 'long', 'DwmGetWindowAttribute', 'hwnd', $hWin, 'dword', $DWMWA_SYSTEMBACKDROP_TYPE, 'ptr', DllStructGetPtr($tResult), 'int', DllStructGetSize($tResult))

ConsoleWrite('DWM_SYSTEMBACKDROP_TYPE: ' & $tResult.DWM_SYSTEMBACKDROP_TYPE & @CRLF)

Possible results:

  0 - DWMSBT_AUTO
  1 - DWMSBT_NONE
  2 - DWMSBT_MAINWINDOW
  3 - DWMSBT_TRANSIENTWINDOW
  4 - DWMSBT_TABBEDWINDOW

 

Or simply use _WinAPI_DwmGetWindowAttribute().
