how to restore default characteristics of terminal in fpc + crt program?

Default terminal characteristics (on linux mint) are: black background and grey font. After launching fpc program with TextColor(Red) and TextBackground(White) and quit out of a program, terminal still has red font and white background. The goal is to find a solution wich will restore default characteristics (black background and grey font) of terminal. thanks for your attention.

Have you tried to run these right before exit the program:
TextColor(White);
// or maybe Gre
y
TextBackground(Black);

you are right, but i would like to find a solution which take into account settings of user`s terminal (TextColor, for example, will be red or black and TextBackground will be blue or green)

My Ubuntu Mate Terminal has black text with white background.
As far as I know Linuxes are very flexible with terminal. Users can install any one she/he likes, and each terminal may has its own default color.
I haven't tried, but maybe this is what you need:

In case it matters, I did a quick test: changing colors (twice, just in case) and then using
NormVideo
did (more or less) work in gnome-terminal.
"More or less" because some colors don't show right (most notably in the background, even if in Black..DarkGray), but that is irrelevant for this thread

Hi!
A Linux terminal is reset to his default values with
Code: Bash
[Select]
[+]
[-]
reset
If you only want to clear the terminal and the color stuff then use
Code: Bash
[Select]
[+]
[-]
clear

the solution is not pretty nice, but worked (from here:
https://wiki.freepascal.org/Executing_External_Programs#TProcess
).
you should paste the code to the relevant places in a program:
Code: Pascal
[Select]
[+]
[-]
uses
process
;
var
reset_process
:
TProcess
;
begin
reset_process
:
=
TProcess
.
Create
(
nil
)
;
reset_process
.
Executable
:
=
'reset'
;
reset_process
.
Options
:
=
reset_process
.
Options
+
[
poWaitOnExit
]
;
reset_process
.
Execute
;
reset_process
.
Free
end
.
