SYNOPSIS

kolor [background foreground cursorcolor]| [-bg background][-fg foreground][-cr cursorcolor] [--verbose]

kolor --help| --usage| --version

DESCRIPTION

Set the background, foreground, and cursor color for terminals and terminal emulators that obey the ANSI in-band signaling control sequences, such as xterm(1).

If no options are supplied, steps through known color names changing the background kolor. Obeys commands such as "back", "top", "next", "quit". Defaults to "next". Enter "help" at the prompt for a full list.

If you use something that filters stdout such as tmux(1) or screen(1) assign kolor(1) output to the initial stdout before starting the program by setting the environment variable OTHERTTY to the output device path. For example:

       export OTHERTTY=‘tty‘
       tmux

Color values may be specified by name or hex value "#RRGGBB" or using RGB syntax, eg. rgb:0000/0000/0000 to rgb:ffff/ffff/ffff.

VARIABLES

By default kolor(1) writes output to the current stdout file. The environment variable OTHERTTY can be used to change the default file. This is commonly required before starting programs that filter stdout, such as tmux(1) and screen(1).

       export OTHERTTY=$(realpath /proc/$$/fd/1)

    kolor rgb:0000/8080/0000 rgb:ffff/ffff/ffff rgb:ffff/0000/0000
