You're making this issue far more complicated than it actually is....
The relevant point ... The crux.... Lee Oswald was NOT wearing a jacket when he left the TSBD.......It was established by the WC that all witnesses who saw Lee after he left the TSBD and when he arrived at the rooming house said that He was wearing a brown shirt... However, Bill Whaley said the man who entered his cab at 12:30 ( Lee was at the TSBD at 12:30) was wearing a jacket ...It was a BLUE jacket. Whaley said the mans trouser were also BLUE and made from the same material as the Jacket.
Bottom Line.... Lee Oswald was not wearing a BLUE jacket nor were his trousers BLUE.... Whaley's passenger was NOT Lee Oswald.
Whaley didn't say the jacket and trousers were blue.
Mr. BALL. Did you notice how he was dressed?
Mr. WHALEY. Yes, sir. I didn’t pay much attention to it right then. But it
all came back when I really found out who I had. He was dressed in just
ordinary work clothes. It wasn’t khaki pants but they were khaki material,
blue faded blue color, like a blue uniform made in khaki. Then he had on a
brown shirt with a little silverlike stripe on it and he had on some kind
of jacket, I didn’t notice very close but I think it was a work jacket that
almost matched the pants.
Whaley might have been confused on the matter of there being a "jacket". The shirt was similar to a jacket.
Mr. BALL. When he came in he was in a shirt?
Mrs. ROBERTS. He was in his shirt sleeves.
Mr. BALL. What color was his shirt? Do you know?
Mrs. ROBERTS. I don't remember. I didn't pay that much attention
for I was interested in the television trying to get it fixed.
