SGR 39 — Default foreground color

Byte forms

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

Description

Resets the foreground to the terminal's theme default without disturbing the background, bold/italic/underline, or other SGR state. The complement of `\x1b[49m` (default background). Useful when you want to switch fg colors mid-line without emitting a full SGR 0 reset and re-applying every attribute.

Spec citation: ECMA-48 §8.3.117 (SGR parameter 39)

Examples

printf '\033[1;31mERROR\033[39m bold continues\033[0m\n'

print('\x1b[31mred\x1b[39m default\x1b[0m')

fmt.Print("\x1b[31mred\x1b[39m default\x1b[0m")

console.log('\x1b[31mred\x1b[39m default\x1b[0m')

printf("\x1b[31mred\x1b[39m default\x1b[0m\n");
