the IDirectDrawColorControl::SetColorControls function in the DirextX API ?
Or is this the only way ? Doen any have an sample on how ?

If you want to remove user mode part of directx then you can use direct
calls to kernel part of directx trough Low Level API.

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/winui
/windowsuserinterface/lowlevelclientsupport/dxlowlevelclientsupport.asp

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/winui
/WindowsUserInterface/LowLevelClientSupport/Graphics/NtGdiDdColorControl.asp

If this is not function that you want then you should be able to find
appropriate, since everything goes though these functions.

I don't know if there is any sample. Try searching the net.
But I'm using one of the functions to get HANDLE that I can pass to driver.

I have no idea about the colors.
