Changing the color of the fretboard

I just got Neck Diagrams Pro and must say, I'm quite impressed. I can't remember how many hours I've spent over the years making diagrams of the scales and chords I wanted using a photo program.

I do have one question, though. Is there a way to change the fretboard color from yellow to a color that looks more like an actual fretboard? I know one can change fretboard color via the Windows Color selector but that's not what I'm looking for (unless anyone has found a color that is more like a guitar fretboard - some RGB that works).

For some reason, I find the default yellow color distracting.

Thanks,
Jim
