Every common string-literal form so you can paste-and-search either direction.

Description

Restores the background to the terminal's theme default without disturbing the foreground, bold/italic/underline, or other SGR state. The complement of `\x1b[39m` (default foreground). Commonly used to end a 'banner' line (colored background) and return to the normal terminal background without resetting text color.

Spec citation: ECMA-48 §8.3.117 (SGR parameter 49)

Examples

printf '\033[41;37m WARNING \033[49m text\033[0m\n'

fmt.Print("\x1b[41mred bg\x1b[49m default bg\x1b[0m")
