Dear Martin,
There's a big difference between passively misremembering the shade of a jacket and actively remembering the actions of a person who is not only in an unusual hurry but has just put on said jacket and is in the process of zipping it up as he rushes out the door.

Nice try, but no cigar. She said the jacket was dark from the beginning and her lack of powers of observation are clear when you read her affidavit in which she says that she couldn't describe the clothing Oswald was wearing when he entered the rooming house.
No, why in the world would she not be able to describe Oswald's clothing as he came in as well as when he left. She can't even describe the jacket, gets the color wrong and only makes a comment about him zipping up a jacket. Even worse, Roberts, by her own admission, wasn't paying much attention and the circumstances as she described justify the conclusion that she only saw Oswald for a few seconds as he opened the front door and walked out.
Besides, the grey jacket wasn't even in the rooming house on Friday morning, but in Irving instead.
It's amazing that anybody would blindly accept the statement about one particular item from a woman with bad vision, who wasn't paying attention, got everything else wrong and who her employer described as somebody who makes up stories.
