I would suggest a light gray wash to highlight the panels. Keep it very light as you can always make it progressively darker unitl you get the effect you want.
Not sure what you'd wanty ot achieve on the geodesic pattern. I personally wouldn't do anything but if you did want to highlight them, you could try applying a thin wash of a slightly darker base colour (green or gray, depending where you are) and then wiping it off lightly, leaving the wash in the low points.
