SGR 40–47 — Background color (8 basic)

Byte forms

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

Description

Background equivalents of 30–37. 40 black, 41 red, 42 green, 43 yellow, 44 blue, 45 magenta, 46 cyan, 47 white. SGR 49 resets the background to the terminal default. Like the foreground, the rendered RGB depends on the terminal color scheme.

for c in range(40, 48): print(f'\x1b[{c}m  \x1b[0m', end='')

for c := 40; c <= 47; c++ { fmt.Printf("\x1b[%dm  \x1b[0m", c) }

for (let c = 40; c <= 47; c++) process.stdout.write(`\x1b[${c}m  \x1b[0m`)
