proposal

The console log could have alternating colors to improve readability:

line 1: white
line 2: gray
line 3: white
line 4: gray
line 5: white
line 6: gray
etc.

rationale

I find it a bit difficult to read, when the screen is full of text: Alternating colors would improve readability IMO:

[Zirro]

Showing alternating colors for each line sounds like it would be more within the domain of the terminal emulator itself - by applying a theme for example - rather than the textual interface of the application running within it.

The common way to use color to increase CLI readability looks to be by coloring parts of the text itself, depending on the type of output it represents. The output from aria2 is a good example of this, and yt-dlp could probably make good use of it too (as long as an option to turn it off is also provided for those who’d prefer that).

Ok, I see what you mean now.

But as you point out, you already use colors for some output (apparently not ouf of scope). I don’t yet get why my proposal is any different from what you are already doing (highlighting some stuff).

Users could still turn this behaviour on/off in the options or override that with a theme as shown in your stackoverflow link, right?

So in case you agree that it’s useful for better readability, is there any offsetting conflict/downside/problem that led to your decision ?
