Hi, Thank you for a wonderful library!

I want the background color to be fixed when using Textview with SetDynamicColors set to true.

For example, if the terminal's background color is not white or black, running an external command like the bat command with color=always and TranslateANSI to display it.

Please let me know what you think about my request.

I'm not completely sure I understand. Does the screenshot show tview with bat's output piped into it using TranslateANSI? And if so, do you want these grey bars or don't you want them?

I’m sorry I was misunderstanding.

I thought the terminal background color was reflected in the result when I run bat command with --color=always, which was wrong.
Actually, only the foreground color was specified and the background color was not specified.

It was gray because the background color (bat result) was not set and the background color of the terminal was reflected.

Setting the TextView background color to tcell.ColorDefault used the terminal background color (https://github.com/rivo/tview/blob/master/box.go#L337), which solved this problem.
