There are people that want to respond to another's post a little at a time....

and so what they do is post in colors so as to show what the other person said, and then in a different color for what they say in response.

The problem is, that unless you always identify at the start of the post who is speaking and in what color the quotations will appear in , you only end up with a mess!
Your posted comments just look like a bunch of colors in them that have no way to be understood by someone else who is unaware of what is being talked about or who said what?.

all we see is one sentence in one color,

and the next sentence in another color....

While that looks nice and colorful, it also is meaningless to anyone else wanting to follow along.
