Tan would be good.
I just suggested velcro because the zippers seem to be requiring quite a large border.
I think I know the screening fabric - it's probably the same they used on my canvas.
If you're using it all the time, you can even modify what you have to add a zipper down the middle, which may be easier going through. Shouldn't require a wide seam.
I don't have a picture of my screening, but the link below shows the cockpit canvas. A rear wall can be zipped onto the rear top and sides of the canvas to seal the forward part of the cockpit and the cabin. It's made in three equal sections, so there is kind of a doorway through the center. Each section is screening on the top half and canvas below. The sections are zipped together. We don't use it during the day, although closer to the ocean beaches green flies can be a problem during the day.
