While messing with my Linux console recently, I stumbled upon the
page. Apparently there are Linux-specific escape codes to redefine the color
palette. Awesome! I’ve always preferred the
“Tango” terminal palette
that recently became the default in
gnome-terminal. Now I can use it
outside of X.
Update: Apparently PuTTY supports these escapes as well.
Using the escape codes to change the palette is quite laborious, so I decided to write a small program to make it easier to switch between various palettes. You can find it here.
There is one problem though. The Linux console doesn’t allow you to set the default foreground/backround colors independently of the color palette, as you can do in most GUI terminal emulators. In the absence of any ANSI color espaces, Linux uses the first and last colors of the palette for the background and foreground (text), respectively. This means that if I were to reuse the Tango palette verbatim in the Linux console, the background would be dark grey and the text would be almost white. This makes man pages harder to read, and I prefer a black background with medium gray text anyway, as is the default in the Linux console. To solve this, I created a palette called “tango-dark” with the first color black and the last color medium grey, and called the unmodified palette “tango-light”.
In addition to the
gnome-terminal palettes (rxvt, tango, xterm), I also
added KDE Konsole’s palette, as well as the color palette used by the
since it mostly fits the ANSI palette (it has black listed twice, so I
replaced one with a dark grey color, which it was missing).
So, assuming Perl is installed, the program can be installed on most distributions in the following manner:
$ cpan -i App::ConPalette
$ conpalette --help
