    Since
    [ncurses-6.0-20180121](http://lists.gnu.org/archive/html/bug-ncurses/2018-01/msg00045.html),
    terminfo began to support the 24-bit True Color capability under the name of
    "RGB". You need to use the "setaf" and "setab" commands to set the foreground
    and background respectively.
    # Truecolor Detection

    # True Color Detection
    ## Checking for COLORTERM

    There will be no reliable way to detect the "RGB" flag until the new release of
    terminfo/ncurses. S-Lang author added a check for $COLORTERM containing either
    "truecolor" or "24bit" (case sensitive). In addition,
    [VTE](https://bugzilla.gnome.org/show_bug.cgi?id=754521),
    [Konsole](https://bugs.kde.org/show_bug.cgi?id=371919) and
    [iTerm2](https://gitlab.com/gnachman/iterm2/issues/5294) set this variable to
    "truecolor". It has been in VTE for a while and but is relatively new, being
    still git-only in Konsole and iTerm2).

    This is obviously not a reliable method, and is not forwarded via sudo, SSH etc.
    However, whenever it errs, it errs on the safe side. It does not advertise
    support when it is actually supported. App developers can freely choose to
    check for this same variable, or introduce their own method (e.g. an option in
    their config file). They should use whichever method best matches the overall
    design of their app. Checking $COLORTERM is recommended though since it will
    lead to a more seamless desktop experience where only one variable needs to be
    set. This would be system-wide so that the user would not need to set it
    separately for each app.
    [iTerm2](https://gitlab.com/gnachman/iterm2/issues/5294) all advertise
    truecolor support by placing `COLORTERM=truecolor` in the environment of the
    shell user's shell. This has been in VTE for a while, but is relatively new in
    Konsole and iTerm2 and has to be enabled at compile time (most packages do not,
    so you have to compile them yourself from the git source repo).

    The S-Lang library has a check that `$COLORTERM` contains either "truecolor" or
    "24bit" (case sensitive).

    Terminfo has supported the 24-bit TrueColor capability since
    [ncurses-6.0-20180121](http://lists.gnu.org/archive/html/bug-ncurses/2018-01/msg00045.html),
    under the name "RGB".
    You need to use the "setaf" and "setab" commands to set the foreground and
    background respectively.

    Having an extra environment variable (separate from `TERM`) is not ideal: by
    default it is not forwarded via sudo, ssh, etc, and so it may still be
    unreliable even where support is available in programs. (It does however err on
    the side of safety: it does not advertise support when it is not actually
    supported, and the programs should fall back to using 8-bit color.)

    These issues can be amelorated by adding `COLORTERM` to:
    * the `SendEnv` list in `/etc/ssh/ssh_config` on ssh clients;
    * the `AcceptEnv` list in `/etc/ssh/sshd_config` on ssh servers; and
    * the `env_keep` list in `/etc/sudoers`.

    Despite these problems, it's currently the best option, so checking
    `$COLORTERM` is recommended since it will lead to a more seamless desktop
    experience where only one variable needs to be set.

    App developers can freely choose to check for this variable, or introduce their
    own method (e.g. an option in their config file). They should use whichever
    method best matches the overall design of their app.

    Ideally any terminal that really supports truecolor would set this variable;
    but as a work-around you might need to put a check in `/etc/profile` to set
    `COLORTERM=truecolor` when `$TERM` matches any terminal type known to have
    working truecolor.

    ```lang=sh
    case $TERM in
    iterm |\
    linux-truecolor |\
    screen-truecolor |\
    tmux-truecolor |\
    xterm-truecolor ) export COLORTERM=truecolor ;;
    vte*)
    esac
    ```

    ## Querying The Terminal

    A more reliable method in an interactive program which can read terminal
    responses, and one that is transparent to things like sudo, SSH, etc.. is to
    simply try setting a truecolor value and then query the terminal to ask what
    color it currently has. If the response replies the same color that was set
    then it indicates truecolor is supported.
    In an interactive program that can read terminal responses, a more reliable
    method is available, that is transparent to sudo & ssh.

    Simply try sending a truecolor value to the terminal, followed by a query to
    ask what color it currently has. If the response indicates the same color as
    was just set, then truecolor is supported.

    If the response indicates an 8-bit color, or does not indicate a color, or if
    no response is forthcoming within a few centiseconds, then assume that
    truecolor is not supported.

    ## Querying The Terminal

    A more reliable method in an interactive program which can read terminal
    responses, and one that is transparent to things like sudo, SSH, etc.. is to
    simply try setting a truecolor value and then query the terminal to ask what
    color it currently has. If the response replies the same color that was set
    then it indicates truecolor is supported.

    ```bash
    $ (echo -e '\e[48:2:1:2:3m\eP$qm\e\\'; xxd)

    ^[P1$r48:2:1:2:3m^[\
    00000000: 1b50 3124 7234 383a 323a 313a 323a 336d .P1$r48:2:1:2:3m
    ```
    Here we ask to set the background color to `RGB(1,2,3)` - an unlikely default
    choice - and request the value that we just set. The response comes back that
    the request was understood (`1`), and that the color is indeed `48:2:1:2:3`.
    This tells us also that the terminal supports the colon delimiter. If instead,
    the terminal did not support truecolor we might see a response like
    ```
    ^[P1$r40m^[\
    00000000: 1b50 3124 7234 306d 1b5c 0a .P1$r40m.\.
    ```
    This terminal replied the color is `40` - it has not accepted our request to
    set `48:2:1:2:3`.
    ```
    ^[P0$r^[\
    00000000: 1b50 3024 721b 5c0a .P0$r.\.
    ```
    This terminal did not even understand the DECRQSS request - its response was
    `0$r`. We do not learn if it managed to set the color, but since it doesn't
    understand how to reply to our request it is unlikely to support truecolor
    either.

    Colours in terminal
    ==================
    It's a common confusion about terminal colours... Actually we have this:

    There exists common confusion about terminal colors. This is what we have right now:

    - ANSI escape codes: 16 color codes with bold/italic and background
    - 256 color palette: 216 colors + 16 ANSI + 24 gray (colors are 24-bit)
    - 24-bit true color: "888" colors (aka 16 milion)

    ```bash
    printf "\x1b[${bg};2;${red};${green};${blue}m\n"
    ```

    The 256 colour palete is configured at start, and it's a 666 cube of
    colours, each of them defined as a 24bit (888 rgb) colour.
    The 256-color palette is configured at start and is a 666-cube of colors,

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

    Since [ncurses-6.0-20180121](http://lists.gnu.org/archive/html/bug-ncurses/2018-01/msg00045.html) terminfo started to support 24-bit truecolor capability under the name of "RGB" - you need to use the "setaf" and "setab" commands to set foreground and background correspondingly.

    Detection
    =========

    There's no reliable way until the new release of terminfo/ncurses. After that the "RGB" flag should be available for detection. S-Lang author added a check for $COLORTERM containing either "truecolor" or "24bit" (case sensitive). In turn, [VTE](https://bugzilla.gnome.org/show_bug.cgi?id=754521), [Konsole](https://bugs.kde.org/show_bug.cgi?id=371919) and [iTerm2](https://gitlab.com/gnachman/iterm2/issues/5294) set this variable to "truecolor" (it's been there in VTE for a while, it's relatively new and maybe still git-only in Konsole and iTerm2).

    This is obviously not a reliable method, and is not forwarded via sudo, ssh etc. However, whenever it errs, it errs on the safe side: does not advertise support whereas it's actually supported. App developers can freely choose to check for this same variable, or introduce their own method (e.g. an option in their config file), whichever matches better the overall design of the given app. Checking $COLORTERM is recommended though, since that would lead to a more unique desktop experience where the user has to set one variable only and it takes effect across all the apps, rather than something separately for each app.

    Improper support for true colors
    --------------------------------

    * [mlterm](http://mlterm.sourceforge.net) - build with **--with-gtk=3.0** configure flag - approximates colors to 512 embedded palette https://sourceforge.net/p/mlterm/bugs/74/

    Parsing ANSI colour sequences, but approximating them to 256 palette
    -------------------------------------------------------------------

    * xterm (though doing it wrong: "it uses nearest colour in RGB colour space, with a usualfalse assumption about orthogonal axes")
    * [urxvt aka rxvt-unicode](http://software.schmorp.de/pkg/rxvt-unicode.html) - since [Revision 1.570](http://cvs.schmorp.de/rxvt-unicode/src/command.C?revision=1.570&view=markup&sortby=log&sortdir=down) http://lists.schmorp.de/pipermail/rxvt-unicode/2016q2/002261.html (Note there is a restriction of colors count at once still)
    * linux console (since v3.16): https://github.com/torvalds/linux/commit/cec5b2a97a11ade56a701e83044d0a2a984c67b4


    Note about colour differences: a) RGB axes are not orthogonal, so you cannot use sqrt(R^2+G^2+B^2) formula, b) for colour differences there is more correct (but much more complex) [CIEDE2000](http://en.wikipedia.org/wiki/Color_difference#CIEDE2000) formula (which may easily blow up performance if used blindly) [2].
    Since
    [ncurses-6.0-20180121](http://lists.gnu.org/archive/html/bug-ncurses/2018-01/msg00045.html),
    terminfo began to support the 24-bit True Color capability under the name of
    "RGB". You need to use the "setaf" and "setab" commands to set the foreground
    and background respectively.

    # True Color Detection

    There will be no reliable way to detect the "RGB" flag until the new release of
    terminfo/ncurses. S-Lang author added a check for $COLORTERM containing either
    "truecolor" or "24bit" (case sensitive). In addition,
    [VTE](https://bugzilla.gnome.org/show_bug.cgi?id=754521),
    [Konsole](https://bugs.kde.org/show_bug.cgi?id=371919) and
    [iTerm2](https://gitlab.com/gnachman/iterm2/issues/5294) set this variable to
    "truecolor". It has been in VTE for a while and but is relatively new, being
    still git-only in Konsole and iTerm2).

    This is obviously not a reliable method, and is not forwarded via sudo, SSH etc.
    However, whenever it errs, it errs on the safe side. It does not advertise
    support when it is actually supported. App developers can freely choose to
    check for this same variable, or introduce their own method (e.g. an option in
    their config file). They should use whichever method best matches the overall
    design of their app. Checking $COLORTERM is recommended though since it will
    lead to a more seamless desktop experience where only one variable needs to be
    set. This would be system-wide so that the user would not need to set it
    separately for each app.

    [1] https://en.wikipedia.org/wiki/ANSI_color

    Currently, there is no support for the 24-bit colour descriptions in the terminfo/termcap database and utilites.
    See the discussion thread here: https://lists.gnu.org/archive/html/bug-ncurses/2013-10/msg00007.html
    Since [ncurses-6.0-20180121](http://lists.gnu.org/archive/html/bug-ncurses/2018-01/msg00045.html) terminfo started to support 24-bit truecolor capability under the name of "RGB" - you need to use the "setaf" and "setab" commands to set foreground and background correspondingly.

    Detection
    =========

    There's no reliable way, and ncurses/terminfo's maintainer expressed he has no intent on introducing support. S-Lang author added a check for $COLORTERM containing either "truecolor" or "24bit" (case sensitive). In turn, [VTE](https://bugzilla.gnome.org/show_bug.cgi?id=754521), [Konsole](https://bugs.kde.org/show_bug.cgi?id=371919) and [iTerm2](https://gitlab.com/gnachman/iterm2/issues/5294) set this variable to "truecolor" (it's been there in VTE for a while, it's relatively new and maybe still git-only in Konsole and iTerm2).
    There's no reliable way until the new release of terminfo/ncurses. After that the "RGB" flag should be available for detection. S-Lang author added a check for $COLORTERM containing either "truecolor" or "24bit" (case sensitive). In turn, [VTE](https://bugzilla.gnome.org/show_bug.cgi?id=754521), [Konsole](https://bugs.kde.org/show_bug.cgi?id=371919) and [iTerm2](https://gitlab.com/gnachman/iterm2/issues/5294) set this variable to "truecolor" (it's been there in VTE for a while, it's relatively new and maybe still git-only in Konsole and iTerm2).

    This is obviously not a reliable method, and is not forwarded via sudo, ssh etc. However, whenever it errs, it errs on the safe side: does not advertise support whereas it's actually supported. App developers can freely choose to check for this same variable, or introduce their own method (e.g. an option in their config file), whichever matches better the overall design of the given app. Checking $COLORTERM is recommended though, since that would lead to a more unique desktop experience where the user has to set one variable only and it takes effect across all the apps, rather than something separately for each app.
