Not sure what you would see other than a grayed out post.

lots of front end tools we can use to see what is happening, which we can’t with pictures.

My real question is why manually editing the color code in the CSS files doesn’t have any effect.

could be loads of things, including caching as Chuckie says, theme and child theme issue or other things.
