-Sometimes setting 'guicolors' is not enough and one has to set the |t_8f| and
-|t_8b| options explicitly. Default values of these options are
-`^[[38;2;%lu;%lu;%lum` and `^[[48;2;%lu;%lu;%lum` (replace `^[` with real
-escape) respectively, but it is only set when `$TERM` is `xterm`. Some
-terminals accept the same sequences, but with all semicolons replaced by
-colons (this is actually more compatible, but less widely supported). These
-options contain printf strings, with |printf()| (actually, its C equivalent
-hence `l` modifier) invoked with the t_ option value and three unsigned long
-integers that may have any value between 0 and 255 (inclusive) representing
-red, green and blue colors respectively.
