The idea that a witness could confuse ‘tan’ with ‘burgundy’ is a premise only a clueless person or a troll would champion. You could argue a witness could confuse ‘black’ with ‘white’. Those colors are as similar as ‘tan’ and ‘burgundy’. Nevertheless, some would say you really can confuse the two. The problem is, people who say that are disconnected from reality. In the real world, if a person is unable to differentiate between two diametrically different colors, then nothing else they say can be relied upon. They are simply worthless observers.
You elucidate so well. (is that the right word?? or should I say write word??)
You must be a writer. ....oh wait....
