As much as I appreciate the time and effort Magnoli's put into this, I'd really rather wait until it's right.
The tie isn't a straight up purple, it's a blue with a hint more purple than the sample shown. This isn't just a lighting issue - look at the color of the tweed. In the shots posted, the tweed looks pretty dead on to how it looks in real life, and the tie is blue with just a hint of purple.
Again, all the hard work is appreciated, but there's no sense in leaving it at 80% when it could easily be closer.
