I know it doesn't matter much for a functional item, but the olive color is more of a dark olive drab grey green. In low lighting it looks black. In bright light it is still much darker than typical army green. I wanted the lighter green, in part to absorb less sunlight, and to look good with my paint color.Will post again if I get to test them on our Van/RV. They seem very sturdy and flexible enough, but my inspection won't compare to driving on them.
