I agree with sdsester, and Ben I guess. This is a fool's errand. The color that was seen on the TV screen was the color as it represented in that room and lighting, rendered by the camera's interpretation of it, influenced by any later editing software or processes, and finally shown to you through a monitor which interpreted that color in it's own way. The actual color that she saw could be quite different in reality. I would take her to a paint store to look at the their color display and start from scratch. Even then the color may be slightly different on the chip in the store than it looks on your wall. It wouldn't even be hard to believe that an experienced long term color mixer/matcher might even know whose color that is. I've thrown color names at them before and was surprised to find they knew them, but I'm fortunate to have a BM dealer that I'm sure is a rarity as far as the staff goes.
