Nota Bene -s-.
I've mentioned it before. Ever go by a place time and again, then one day notice something that you never saw clearly before?
For years I drove past old buildings in my area. One day, I was stopped and looked up. There was the ornate cornice to the building, a brick structure. It housed small businesses, including an elderly tailor who was an artist for detail.
This notice added such depth and scope to something already worthwhile.
There are other instances such as a certain statue, a particular house or even colors that vary. A picture can get painted in as a result.
Akin to this is indeed color. Say you see a red car. Almost suddenly, there is a profusion of red cars. Or certain car brands and makes that then become noticeable.
It's not magic. It is merely awareness.
When your neck's on a swivel, you have the ability to notice a larger world.
I see said the blind man -s-.
The mind's eye is put on notice.
