Color fix

I hadn’t realized MacOS still had a different way of interpreting image colors than Windows. So the green area at the right side of my title bar (right of the photo) looked clipped when it shouldn’t have. Fixed this with a solid-green background image. Can’t check right now, but I’ll ask Marius at the office to check that for me. Changed the color of the title too, now that the brown headers are (almost always) gone.
