[slang-users] Support for True Color (16 millions colors)


Now more terminals bring support for 16 million colors (see references below).

Here's a test case for terminal:

printf "\x1b[38;2;255;100;
0mTRUECOLOR\x1b[0m\n"

It's a common confusion about terminal colors... Actually we have this:

plain ascii
ansi escape codes (16 color codes with bold/italic and background)
256 color palette (216 colors+16gray + ansi) (colors are 24bit)
24bit true color (8*8*8 colors (aka 16 milion)

The 256 color palete is configured at start, and it's a 6*6*6 cube of
colors, each of them defined as a 24bit (8*8*8 rgb) color.

This means that current support can only display 256 *different*
colors in the terminal, while truecolor means that you can display 16
milion different colors at the same time.

Truecolor escape codes doesnt uses a color palete. It just specifies
the color itself.

Here is terminals discussions:

Now supporting truecolor:

st (from suckless) -  http://lists.suckless.org/dev/1307/16688.html
konsole (already fixed)  https://bugs.kde.org/show_bug.cgi?id=138740
all libvte based terminals:  https://bugzilla.gnome.org/show_bug.cgi?id=704449
sakura  https://bugs.launchpad.net/sakura/+bug/1202564
