"\e]50.." is used in Konsole to change session properties on the fly(see the konsoleprofile script). "\e]10;.." is supported according to the code, but it seems to be meant to only change the foreground color. Also, the form of "rgb:ff/ff/ff" is still not supported. See bug 138740 Created attachment 183379 [details]
A screen recording of Konsole and kitty side-by-side showcasing the bug in Konsole.
Setting color via the form "rgb:ff/ff/ff" is still not possible on Current Konsole version (25.04.3).
The attached video showcases Konsole and kitty's behaviors when trying to set the colors via this form side-by-side.
Along with that, "tput reset" doesn't seem to properly reset Konsole when its colors are set via the "#rrggbb" form.

Version: 2.0 (using KDE 4.0.5) Installed from: Ubuntu Packages OS: Linux The problem is that konsole does not seem to completely emulate xterm compatibility. It seems to emulate positioning and things, but that's about it. For instance, this test function in bash will dynamically change the font size in xterm, but fails in konsole. (It fails in gnome-terminal as well, FYI.) function font() { font_size=11 font_weight="medium" if [ "$1" == "big" ] || [ "$2" == "big" ]; then font_size=26; fi if [ "$1" == "bigbig" ] || [ "$2" == "bigbig" ]; then font_size=34; fi if [ "$1" == "bold" ] || [ "$2" == "bold" ]; then font_weight="bold"; fi _font="\e]50;-*-lucidatypewriter-$font_weight-r-*-*-$font_size-*-*-*-*-*-iso8859-*\007" echo -ne "$_font" } # execute with '$ font big' I also have the ability to change my background color with escape sequences in xterm, but not so in konsole. For instance, this bash code works in xterm: w='rgb:ff/ff/ff' # white g='rgb:aa/aa/aa' # light/linux gray b='rgb:00/00/00' # black w_background="\e]10;$b;$w;$b;$b;$b;$b;$w;$w\007" g_background="\e]10;$b;$g;$b;$b;$b;$b;$w;$w\007" b_background="\e]10;$g;$b;$b;$b;$b;$b;$w;$w\007" # execute with '$ echo -ne $w_background' # execute with '$ echo -ne $g_background' # execute with '$ echo -ne $b_background' A reference for the different options and escape sequences: http://rtfm.etla.org/xterm/ctlseq.html I think this bug is not the same, but is related to these bugs about TERM=xterm http://bugs.kde.org/show_bug.cgi?id=145977 http://bugs.kde.org/show_bug.cgi?id=169013 Also: Konsole 2.0 (Using KDE 4.0.3) $ dpkg -l *kde4* | grep konsole ii konsole-kde4 4:4.0.3-0ubuntu2 X terminal emulator for KDE 4 $ uname -a Linux hani 2.6.24-19-generic #1 SMP Fri Jul 11 21:01:46 UTC 2008 x86_64 GNU/Linux $ lsb_release -a No LSB modules are available.
