Just as a matter of interest what colour lens do you have in your
sunglasses?

Grey lenses and I was not wearing sunglasses that day in late October with large lenticular and rotor clouds high above. The glider color was not brilliant International Orange, it looked faded and dull from sun exposure. Plus I only gave it a quick glance, just long enough to ascertain the relative position and recognize the color as being orange. It was not that close either.
