FZ1000M2

I have a problem and can’t find the switch to return it to the original setup.
When I look at the screen or thru the viewfinder the image is in black & white, not color. After the shot, the color comes back. This is particularly difficult if I’m taking pictures of Red Roses since everything, blooms and leaves all blend together into a single B&W image and the blooms disappear. Fn8 will flip on the WBc (White Balance Color) screen but it goes back to B&W as soon as I touch the trigger to take button. After the shot I see the image in color again.
