"Tortoise" or "Horn?"
This is an excellent photo, from an Asian website, of a frame almost identical to my Lunor 215 color 03. If you saw a frame such as this would you label it tortoiseshell or horn (e.g. buffalo horn)? It has the basic parallel lines such as horn typically has but the coloring is well within the tortoiseshell range. I have, however, seen frames of authentic horn with similar coloring - sometimes solid.
Lunor is fabulous but the frame is, admittedly, acetate. However, I'm just wondering the overall impression the frame gives as to material. Lunor avoids the question by calling the color "light havana." Other eyewear makers use "Havana" also in labeling their frames.
